Problems solved by technology

[0002] At present, the structure of the furnace sill is to pour the furnace foundation on the furnace bottom steel plate. The furnace foundation has always been made in a one-time pouring method. Scratching, under normal circumstances, the service life of the furnace sill does not exceed 8 months, and the service life of the furnace slope and the bottom of the furnace base is longer than this time, because it is poured as a whole, when replacing the furnace sill, the furnace needs to be dismantled as a whole foundation re-poured, resulting in greater waste

Embodiment Construction

[0019] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, but not for limiting the protection scope of the present invention.

[0020] Such as Figure 1-3 As shown, a smelting furnace threshold for casting and rolling includes a furnace base 2, a steel frame structure 22 with a cast iron tank 21 on the top is arranged in the furnace base 2, the bottom end of the steel frame structure is fixed on a horizontal steel plate, and the furnace base 2. The top is flush with the top of the cast iron tank 21. The furnace base 2 is sloped toward the inner side of the furnace. The outer side of the furnace base is provided with a steel plate layer 1. One end of the horizontal steel plate is connected to the steel plate layer, and the other end is connected to a vertical steel plate. There is a gap between...

Abstract

The invention discloses a smelting furnace threshold for casting and rolling. The top of the tank is even, and the furnace base is sloped towards the inner side of the furnace. There is a steel plate layer on the outside of the furnace base. One end of the horizontal steel plate is connected to the steel plate layer, and the other end is connected to a vertical steel plate. The gap, the furnace threshold also includes a prefabricated block, the prefabricated block is a right-angled trapezoid with a raised bottom edge on the cross section, the raised part is located in the cast iron groove, and the hypotenuse of the right-angled trapezoid is aligned with the inner slope of the furnace foundation; the invention also discloses a The method for making the furnace threshold includes casting steps and assembling steps of the furnace foundation; the furnace threshold is provided with prefabricated blocks on the furnace foundation. The maintenance time is shortened, and the service time of the single pouring of the furnace is extended at the same time.

Description

technical field [0001] The invention relates to the field of aluminum processing, in particular to a smelting furnace threshold for casting and rolling, and also relates to a method for manufacturing the smelting furnace threshold for casting and rolling. Background technique [0002] At present, the structure of the furnace sill is to pour the furnace foundation on the furnace bottom steel plate. The furnace foundation has always been made in a one-time pouring method. Scratching, under normal circumstances, the service life of the furnace sill does not exceed 8 months, and the service life of the furnace slope and the bottom of the furnace base is longer than this time, because it is poured as a whole, when replacing the furnace sill, the furnace needs to be dismantled as a whole The foundation is poured again, resulting in a large waste. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide a smelting furnace threshold f...
