Abstract

The invention discloses a steel ingot slow cooling cover with controllable cooling speed, which comprises a box body, the box body includes an upper cover and a side wall, the rear end of the upper cover is hinged with the upper end of the side wall, and the front end of the upper cover is provided with a door lock Buckle, the upper cover can be opened or closed through the door lock; both the side wall and the upper cover of the box body include an outer layer, an inner layer and a heat insulation layer between the outer layer and the inner layer; There is at least one ventilation hole; it also includes a temperature sensor, an air compressor, a heater, a gas pipe and a PLC controller. Both the air compressor and the air compressor are electrically connected to the PLC controller. The slow cooling cover of the present invention has a good slow cooling and heat preservation effect, so that the steel ingot is cooled according to the cooling curve, which is beneficial to ensure and improve the quality of the steel ingot, and the cooling speed is automatically regulated by the PLC controller, and the degree of automation is high, so that the cooling process can be controlled in real time, reducing Ingot scrap rate.

Description

technical field [0001] The invention relates to the technical field of steel ingots, in particular to a steel ingot slow cooling cover with controllable cooling speed. Background technique [0002] High-quality structural alloy steel is the main material for manufacturing important mechanical parts and has a wide range of uses. Therefore, the requirements for the chemical composition, internal quality and surface quality of important steel ingots are very strict. To ensure the chemical composition, internal quality, and especially the purity of steel, many iron and steel production enterprises currently use a slow cooling process to cast in ingot molds. The steel ingots are slowly cooled to ensure the cooling curve of the steel ingots, thereby ensuring the purity of the steel ingots. Generally, the steel ingot is covered with a slow cooling cover to reduce its cooling rate to ensure the cooling curve. [0003] However, the structure of the slow cooling cover in the prior a...
