Abstract

The invention relates to a casting method of a cast steel cooling plate, which adopts a cast steel material to cast a cooling plate base body and a cooling water pipe. The casting method comprises the following steps: adding a slagging agent and a silicon iron alloy block in molten steel for casting steel; putting the cooling water pipe into a casting model, sheathing a pipe sleeve on the coolingwater pipe and leading a liquid cold medium and a composite solid cooling medium to pass through the cooling water pipe; using molten steel for casting steel to cast the cooling plate base body, and casting the middle part of the cooling water pipe into the cooling plate base body; leading the casting model to be horizontal in the modeling process, leading a feeder head to be modeled lopsidedly toward one side and heightening one side of the feeder head of the model after the model is boxed; adopting an upper layer of inner sprue and a lower layer of lower sprue to carry out stepped casting so as to form sequential solidification; and cooling and disassembling the model. The casting method can effectively avoid the cooling water pipe from being penetrated in a fusing manner during the casting process, avoid air gaps from being generated between the base body and the cooling water pipe, avoids refusion and recrystallization, accurately realizes the microfusion of the outer surface of the cooling water pipe, prolongs the service life of the cooling plate, further prolongs the service life of a metallurgical high-temperature kiln, saves production cost and improves the cooling effectand the mechanical performance of the cast steel cooling plate.

Description

technical field

[0001] The invention relates to a metallurgical high-temperature furnace, in particular to a casting method for a cast steel cooling plate used in a metallurgical high-temperature furnace, and belongs to the technical field of metallurgical ironmaking. Background technique

[0002] The cooling plate is a cooling device for the metallurgical high-temperature furnace, which can protect the metallurgical high-temperature furnace from the erosion of the high-temperature fluid in the furnace and mechanical wear, prolong the life of the metallurgical high-temperature furnace, and ensure its safe and stable production. Once there is a problem with the cooling equipment, the metallurgical high-temperature furnace must be completely shut down for maintenance, which will cause major economic losses. Therefore, the life and performance of the cooling plate determine the life of the metallurgical high-temperature furnace, which is an important guarantee for the long life...
