Description

Technical Field

[0001] The utility model relates to a feeding device for steel bar quenching, belonging to the technical field of steel bar quenching. Background Art

[0002] Rebar refers to steel used for reinforced concrete and prestressed reinforced concrete. Its cross-section is round, sometimes square with rounded corners. The quenching of steel is a heat treatment process in which the steel is heated to a critical temperature Ac3 or above Ac1, kept warm for a period of time to make it fully or partially austenitized, and then cooled rapidly to below Ms at a cooling rate greater than the critical cooling rate for martensitic transformation. The steel bar needs to be quenched to increase its hardness before it is made into a product.

[0003] The existing patent number is CN220579333U, which is a feeding device for steel bar quenching. This device adopts a rolling mechanism for feeding, which reduces friction and has low conveying power. The rolling mechanism is not related to the conveying structure in the quenching furnace, so that the furnace door is closed after the steel bar enters the quenching furnace, which is convenient for controlling quenching stability, saving energy, and opening and closing the furnace door is simple and convenient. The device is simple in design and easy to operate. However, although this device can be used for rolling feeding when in use, it does not have an automatic feeding mechanism, and the furnace door needs to be opened and closed repeatedly during the feeding process, which will also cause heat loss and affect the steel bar quenching effect and quenching efficiency; and after the steel bar is placed in the calcining furnace for heating, it is difficult to automatically place the steel bar in the cooling pool for cooling, and after the steel bar is manually placed in the cooling pool, the internal temperature will continue to rise, and the existing structure is difficult to quickly replace the coolant in the cooling pool, which affects the continuous quenching treatment effect of the steel bar, and wastes a large amount of coolant, increasing the cost of steel bar quenching.
