However, in the prior art, the quenching efficiency is not high, and the properties such as rigidity and hardness that the product can achieve after quenching cannot meet the expected situation, and the quenching efficiency is relatively low, and the quenching method is not good enough, resulting in high quenching cost
At the same time, after the product is heated, staff are required to assist in hoisting the product, which is inefficient and poses a great safety hazard

Embodiment 1

[0029] Embodiment one: see figure 1 , 2 As shown, a low-impurity ultra-low carbon stainless steel quenching process, the steps are:

[0030] ① Put the billet into the heating furnace and heat it to 1060℃~1200℃;

[0031] ② Then pull out the sliding seat at the bottom of the heating furnace. During the process of pulling out the sliding seat, the two sides of the bottom of the blank will slide to the two sides of the hanging basket, so that the hanging basket can lift the blank;

[0032] ③ Use the crane to lift the hanging basket. During the lifting process of the hanging basket, the hanging basket can be used to lift the billet and make it out of the sliding seat of the heating furnace;

[0033] ④ Drop to move the billet to the top of the quenching pool, and then lower the billet, so that the high-temperature billet is put into the quenching oil in the quenching pool, and the billet is completely sunk in the quenching oil for quenching work;

[0034] ⑤The initial temperature...

Abstract

The invention discloses a quenching process and device for low-impurity ultra-low-carbon stainless steel. The method includes the steps that: firstly, a blank is put into a heating furnace and heatedto 1060-1200 DEG C; secondly, a sliding seat at the bottom of the heating furnace is pulled out, when the sliding seat is pulled out, the two sides of the bottom of the blank slide to the two sides ofa hanging basket, and thus the hanging basket can lift the blank; thirdly, the hanging basket is lifted through a crane, and in the process of lifting the hanging basket, the blank can be lifted by the hanging basket and thus be separated from the sliding seat of the heating furnace; fourthly, the blank is moved to the position above a quenching bath through the hanging basket, and then lowered,so that the high-temperature blank is put into quenching oil in the quenching bath, and the blank is completely submerged in the quenching oil for quenching; fifthly, the initial temperature of the quenching oil is 80-130 DEG C; and sixthly, quenching is conducted for 1 to 3 minutes and then completed. Through the quenching process and device, the product performance is improved, and potential safety hazards are reduced.

Description

technical field [0001] The invention relates to the production field of metal products, in particular to a low-impurity ultra-low-carbon stainless steel quenching process and a quenching device. Background technique [0002] In order to improve the rigidity and hardness of low-impurity ultra-low carbon stainless steel, it is generally necessary to heat it and then perform a quenching process to improve its rigidity and hardness. However, in the prior art, the quenching efficiency is not high, and the properties such as rigidity and hardness that the product can achieve after quenching cannot meet the expected situation, and the quenching efficiency is relatively low, and the quenching method is not good enough, resulting in high quenching cost . At the same time, after the product is heated, staff are required to assist in hoisting the product, which is inefficient and poses a great safety hazard. Therefore, how to solve the above technical problems is the direction that t...
