Spray quenching unit

Abstract

The invention discloses a spray quenching unit which comprises a quenching water tank, at least two sliding chute boards arranged above the quenching water tank, at least two rotary rollers which are rotatably arranged above the quenching water tank and positioned between every two adjacent sliding chute boards, and a spray chamber arranged above the sliding chute boards, wherein the quenching water tank is communicated with the spray chamber, and a spray quenching hollow chamber is formed between the quenching water tank and the spray chamber; and the spray quenching unit also comprises a lifting device for lifting a spray chamber front door, a lifting device for lifting a spray chamber back door, a spray water main arranged in the spray quenching hollow chamber, and at least one spray pipe arranged on the spray water main. The invention does not need to perform quenching when the opening of the steel cylinder is in the sealed state, and the spray quenching water can not enter the cylinder, thereby avoiding the problem of explosion due to expansion of the heated steel cylinder; and spray quenching mode is designed as pipe-through high-pressure water spray, thereby saving the material, lowering the investment cost and having good use effect.

Description

technical field [0001] The invention relates to a spray quenching device. Background technique [0002] At present, the larger steel cylinder manufacturing enterprises in China generally adopt the immersion quenching process. The steel cylinder is completely rolled into the quenching tank and completely submerged by the quenching liquid to achieve the quenching process. The premise of the current immersion quenching technology must ensure that the cylinder The mouth must be airtight, otherwise, during the immersion and quenching process, water will enter the steel cylinder, and when it enters the tempering furnace, the water in the steel cylinder will suddenly turn into water vapor, which will increase the pressure in the steel cylinder, resulting in an explosion, which will cause Incalculable human and financial losses. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a spray quenching device with...
