A smoke exhaust device for high-speed steel production

Abstract

The invention relates to a smoke discharging device for high-speed steel production. An electric control module adjusts the left-right positions of an electric control smoke inlet partition plate relative to a first smoke inlet channel and a second smoke inlet channel and the downward inclination angle of a dirt discharging flow guiding plate according to comparison of the difference absolute value of the detection result of a smoke inlet flow sensing device and the preset value, accordingly, the smoke inlet partition plate moves in the direction where the smoke inlet flow is small, the spaceof the side where the smoke inlet flow is large is increased, the space of the side where the smoke inlet flow is small is reduced, the smoke inlet flow of the two sides of the smoke partition plate is balanced, and the risks that due to long-time usage, the single-side temperature is likely to be high, pollution is serious, and deformation is likely to happen are avoided; meanwhile, the downwardinclination angle of the dirt discharging flow guiding plate is adjusted, and when the smoke inlet flow of the smoke inlet channel close to one side of a dirt discharging pipeline is large, falling smoke impurities are prevented from being rapidly stacked and blocking the dirt discharging pipeline; and when the smoke inlet flow of the smoke inlet channel away from one side of the dirt dischargingpipeline is large, the falling smoke impurities are promoted to rapidly move towards one side of the dirt discharging pipeline to be stacked.

[0002] The production and molding process of high-performance high-speed steel involves a number of casting and metallurgical processes, including at least oxygen-controlled purification refining-low segregation solidification technology, magnetron electroslag remelting technology and rapid solidification electroslag remelting technology, etc., in the above High-temperature heating process is unavoidable in many casting and metallurgical processes. The smoke generated during the high-temperature heating process needs to be discharged in time through the smoke exhaust device. According to the different casting and metallurgical processes, different smoke exhaust devices should be installed to achieve different cooling temperatures and pollution. However, in the prior art, for the convenience of smoke exhaust, multiple smoke exhaust processes are often concentrated in the same smoke exhaust device, which leads to the fact that two or more smoke inlet pipes are often collected in the same smoke exhaust device And there are smoke barriers between them to avoid smoke passing between each other, and the performance of the high-performance high-speed steel produced and formed each time is different, which will inevitably lead to changes in the smoke flow of multiple smoke inlet pipes, and the pre-set partitions The position of the smoke plate is relatively fixed and cannot be moved according to the change of the smoke flow of each smoke inlet, so there is uneven smoke flow on both sides of the smoke partition, and long-term use is likely to cause excessive temperature on one side, heavy pollution, and easy deformation At the same time, when the position of the smoke baffle is fixed, when the smoke flow rate on one side is too high, it will also cause the internal pressure of the smoke exhaust device to be too high, and in serious cases, it may even lead to the risk of deformation, cracking or even explosion of the smoke exhaust device
