The bolt reinforcement technology is widely used in engineering. At present, it has been developed in underground engineering, slope engineering, structural anti-floating engineering, deep foundation pit engineering, gravity dam reinforcement engineering, bridge engineering, and ground anchoring applications for anti-overturning and seismic engineering. In recent years, China's ongoing high-speed railways, cross-sea bridges, subsea tunnels, subways, wind power and other large-scale infrastructure construction encountered ground treatment, slope reinforcement, underground space structure reinforcement, underwater space structure, etc. Among all the problems, the bolt reinforcement method has been greatly expanded. Like other quenching and tempering, the induction heat treatment and heat treatment production line mainly improves the mechanical properties of the anchor and obtains the desired sorbite structure.

 

Project Introduction:

This project is independently developed and manufactured by Xi'an Boda Electric Furnace Co., Ltd. The quenching and heat treatment production line consists of two parts: quenching and tempering; the quenching heating part is composed of two sets of medium frequency power supplies with different powers and multiple sets of heating induction coils. The total power of the quenching part is 750Kw, the total power of the tempering part is 400Kw, and the bus length reaches 38.62. Meter, in which the spray part consists of three sets of spray rings.

Bar diameter range (mm): Φ30-65

Bar length range (mm): 2000-7500

Bar material: 45, 40Cr, 42CrMo, etc.

Quenching temperature: 750-1200 ° C

Tempering temperature: 500-900 ° C

Hardness range: 25-40HRC

Maximum production capacity: 2t/h

The final hardness uniformity is required to be ±10HB. On the basis of the straightness of the raw material, the straightness requirement of the bar after quenching and tempering is less than 1mm/m.

The spray ring is fully enclosed, which prevents splashing of the spray liquid and facilitates the return of the spray water. The relative position of the grading sprinkler is adjustable, and a sump is used to recover the quenching liquid to avoid splashing of the spray water. Each stage of the sprinkler system has a separate water pump and electronic flow meter to make it controllable.
