Crystallizer cooling device and cooling method thereof

Abstract

The invention discloses a crystallizer cooling device and a cooling method thereof. The crystallizer cooling device comprises a cooling jacket arranged on a crystallizer in a sleeved manner, and a cooling pipe is assembled on a cooling blind hole through a seal fixing sleeve; the cooling pipe comprises a water inlet pipe, the seal fixing sleeve and a water return pipe, and the seal fixing sleeve is arranged at one end of the water inlet pipe in the sleeved manner, and hermetically connected with the water inlet pipe; the other end of the water inlet pipe extends into the cooling blind hole, and a water return clearance is reserved between the other end of the water inlet pipe and the cooling blind hole; the water return pipe is fixedly connected with the side wall of the seal fixing sleeve, and communicates with the water return clearance through the seal fixing sleeve; the water inlet pipe communicates with a main water inlet pipe through an electric regulating valve, and the water return pipe communicates with a main water return pipe; an outlet pipeline of the water return pipe is further provided with a temperature measuring element, and the temperature measuring element and the electric regulating valve are connected with a PID temperature control regulating unit electrically; and closed-loop control over return water temperature can be achieved by the PID temperature control regulating unit through the electric regulating valve.

Description

Technical field [0001] The invention belongs to the technical field of metal casting equipment, and specifically relates to a crystallizer cooling device and a cooling method thereof. Background technique [0002] Continuous casting (including horizontal, upward, downward continuous casting and semi-continuous casting) is an advanced casting method. Its principle is to continuously pour molten metal into a special metal mold called a mold, and solidify The shelled castings are continuously pulled out from the other end of the mold, and castings of any or specific length can be obtained. It can realize continuous casting of bars, pipes and plates. Among them, the cooling device of the mold is very critical, which directly determines the structure and performance of the cast slab. [0003] The traditional mold cooling device adopts an integrated design according to the specifications and shapes of the casting billet. Generally, after the cavity is welded from copper plates, the wat...

Problems solved by technology

Its disadvantages include: 1. Adopting non-standard design, the structure of the cooling device is complex and difficult to process; 2. The cooling device adopts an integral welding method, which is easy to deform during the welding process and has welding stress, which leads to easy deformation during use and short life; 3. Each cooling circuit is connected in series or in parallel, resulting in uneven cooling water flow rate and dead angle; 4. The cooling process is uncontrollable
