Problems solved by technology

[0002] Special-shaped ingots are steel ingots with different specifications and different weights. Usually, they need to be poured separately, which not only occupies the pouring chassis, but also adds a middle injection pipe, and the corresponding consumption of refractory materials and remaining steel will increase.
[0003] In addition, in order to meet the needs of small and medium-sized orders, it is impossible to arrange production for small-sized (batch) orders that are less than one batch of steel
Increased energy consumption and auxiliary material consumption

Abstract

The invention is suitable for the technical field of steel ingot processing, and provides a same-disc pouring process of a special-shaped ingot and the special-shaped ingot. The same-disc pouring process of the special-shaped ingot comprises the following steps that steel ingot molds with different tonnage specifications are designed, and steel ingots with different weight specifications are produced at the same height; at least two kinds of steel ingots with different weight specifications are taken and are separately subjected to melting treatment to obtain at least two kinds of molten steel; and the at least two kinds of molten steel are placed in the same disc to be poured, and the special-shaped ingot is obtained. According to the same-disc pouring process provided by the embodiment,two or more specifications of steel ingots are poured on the same disc by designing the specific ingot type and matching the weight with the height, so that the consumption of refractory materials isreduced, the residual steel amount is reduced, the product quality is improved, the quality is superior to that of multi-disc pouring steel ingots, the labor intensity of bottom plate masonry and pouring workers is reduced, and the direct production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of steel ingot processing, and in particular relates to a same-pan pouring process for special-shaped ingots and the special-shaped ingots. Background technique [0002] Special-shaped ingots are steel ingots with different specifications and different weights. Usually, they need to be poured in separate plates, which not only occupies the pouring chassis, but also adds an intermediate injection pipe, and the corresponding consumption of refractory materials and remaining steel will increase. [0003] In addition, in order to meet the demand for small and medium-sized orders, it is impossible to arrange production for small-sized (batch) orders that are less than one batch of steel. In order to meet the needs of customers, it can only be used with other specifications to prepare the warehouse and accumulate funds. Due to collocation with other specifications, one batch of steel with more than 2 specificatio...
