Carbon steel tubes two type treatment processes

Steel tubes of two types of heat treatment processes

Oil steel pipe manufacturers, who produce high quality steel tubing and the casing has brought great difficulties.

Construction of oil steel pipe heat treating production line can easily purchase low-grade steel pipe J55 heat treatment to improve for the N80,, of the P110, Q125 grade of steel used to solve high-quality steel pipe is difficult to procurement difficulties to meet the steel pipes for the oil production of crude oil production company the high price of crude oil were housing must meet the growing demand from the oil fields is more complicated.

Steel pipe is hanging on the slope outside the hardened surface of the furnace on the bench, who lined up behind the pickup roller kiln with power supply and pull the power off, pull the unit's power will be of steel pipes from the drop-rack load on the quenching of the charge rollers. bit stream to satisfy the charge door, tempering furnace feed roller and the roller bracket charge, at the same time, rapid rotation, the tube is directed into the furnace hardening.

the location of steel tubes in the furnace tempering steel pipe positioning device and PLC control. Steel pipe positioning device usually consists of two photoelectric switches, and the completion of the length of steel pipe measuring the velocity and position it in the oven and the PLC. 3 steel tubes in the furnace in place, and in the oven for the feed roller stops rotating, while the oven revitalization of the beam increases, steel pipes from the furnace cantilever rollers hold up to 180 mm, the level rays of the next 140 (150) mm, and then remove 180mm, steel pipe on the furnace fixed socket of a tooth on an inclined plane of the beam to rotate at a certain angle falls in the tooth sockets of the beams, and then returned to the level to 140 (150) mm to the starting position to complete the activation of forward movement.

Thus, each feeding a beat, walking beams to complete the time to forward movement of the tube in a fixed beam to move forward on a tooth from 180 (200) mm, and the reflection of a certain angle, insulation of heat pipes in the quenching furnace tempering temperature requirements. walking-beam steel pipe assistance to quench furnace rollers cantilever material, feed door, oven hardening material cantilever rollers and quenching of the furnace to feed the video out at the same time, the rapid rotation (maximum VVVF 2m / S). tube furnace rollers passed the high water pressure, in addition to the scale of the device to the roller quenching machine materials, hardening of the material machine roller set two photoelectric switches, the unit became head of the first photoelectric switch, roller brake block of the second photoelectric switch movie stops, the rest of the tube gently against the fixed walls. quenching mechanism for feeding the furnace (Group Las Dayton lever) to the tube care to a group of rotating bearings quenching wheel.

Compliant pressure roller with a hydraulic cylinder to suppress the steel pipe. Steel pipe was caused by the rotating wheel bearings rotate at higher speeds, this time for the solidification of the flap was removed the fuel tank, outside watering pouring, splashing in a three-way valve switching the spray from the holes injected into the steel tube at one end, so that the outside shower, spray rotating quenching. extinguishing time, depending on pipe material and wall thickness, as a rule, 6-3040-650) (in seconds can be arbitrarily set. After quenching, the valve will be located outside the irrigation district denies the fall of the next fire pit, a spray flow of three references into the pit through the relief valve for internal pinch roller spray removed, pull the feeder will pull out the tube, insert a blank water at one end of an empty water to raise the same time, the compressed air from a nozzle Chit empty water into the empty water falling discharge power block device channel will be pull the steel tube and sent back to the furnace charge rollers feed the beat in the quenching of the charge door, stainless steel clip to send back into the oven, transfer mode with a tube furnace quenching in the back of the plate to move forward one step at a thermal tempering temperature of the blend door of the furnace tube to the feed roller gear outside the furnace roller associated with an equalizer feeding roller, a short period of cooling in bed before straightening machines, steel pipes to cool to 450-500 degrees, pulling on the steel pipe straightening machine to send the feed rollers and straightening straightening machine.

require straightening machine has the function of fast open to adapt to straighten break both ends of the steel pipe. These furnaces can be a good heat treatment of steel pipes.

rolling steel pipe plant heat treatment production line design of this heat treatment line is mainly used for oil casing heat treatment, the implementation of API 5CT- in 2001. for the production of high value-added pipe, casing and improve economic efficiency.

after heat treatment, pipe, casing has a higher strength, toughness and corrosion resistance performance, in accordance with international standards, leading position in the domestic design of the following process: from the middle library to be heat-treated steel with a crane in the charging table, and then into the furnace quenching, in accordance with the requirements after the release of high pressure water and the removal of phosphorus transport device is a rotating roller quenching with water, and use multiple sets of compression rollers pressed steel rotation, just above the water at room temperature wash the exterior walls of the tube quenching, steel pipe nozzle spray to extinguish the tube wall, until the temperature reaches the http://www.netgms.com/carbon-steel-pipe.htmlrequired temperature of organizational change, and then lift transport aircraft, steel pipes are transported to the catchment area of the disk, and then feed back to the plate by a steel pipe with the back plate of the sizing mill, hot leveler in the NC cooling bed, cooling, passing in the middle of the library This production line is the key technology and innovation.: (1) the use of systems engineering principles and technology requirements and to optimize the process to all areas of the four thermal processing at the same time, primary and secondary balance, smooth flow, efficiency and low consumption.

(2), outside shower spray technology, along with the water quenching of steel pipes, an expert system software to ensure that reasonable and reliable process parameters during the processing of each grade of steel, seamless steel tubes, thus providing a thermally processed product quality. (3) automatic control, computer information management, total quality control, improve productivity and control. (4) change the oil quenching, water quenching and significantly reduce pollution, save fuel, improve industrial safety, and (5) for investment portfolio optimization and selection of equipment, compared with a full range of equipment imports, maintaining investment in the construction of more than 100 million yuan.
