Alloy baking stove

Abstract

The invention relates to an alloy baking stove which is a device for baking alloy. The alloy baking stove comprises a stove cover, a stove body, a refractory material layer, a heating device, a material unloading device, a material level meter and a thermometer, and is characterized in that the inner refractory layer is provided with an inclined hole; one end of the inclined hole is communicated with a baking chamber, and the other end of the inclined hole is communicated with an annular flue; the angular inclination of the inclined hole is between 20 degrees and 80 degree; 1-10 burners are mounted on a device body; a burning cavity is arranged in each burner; the burning cavities are communicated with the annular flue; and the axis line of each burner is tangential to the central line of the annular flue. The alloy baking stove provided by the invention has a simple structure, is convenient to use, safe and reliable, and has the advantages of good heat preservation effect, uniform alloy heating temperature and high energy utilization rate; and equipment is convenient to install and maintain, automatic control can be realized, material charging and unloading are convenient, the operation cost is low, and heating fume and the alloy can exchange heat sufficiently.

Description

technical field [0001] The invention relates to a baking furnace, in particular to an alloy baking furnace, which is a device for baking alloys and belongs to the metallurgical industry. Background technique [0002] In the process of smelting steel, in order to adjust the composition of molten steel, it is necessary to add an appropriate amount of alloy. The added alloy must have a certain temperature, because if the alloy is added at room temperature, the alloy will contain a large amount of free water and crystal water, so that white spots will appear in the smelted steel forgings, which are a kind of brittle sharp edge. Cracks are extremely harmful. Adding alloys at room temperature will also affect the temperature of molten steel. Therefore, the alloy needs to be heated before being added to molten steel, and now a baking furnace is used to heat the alloy. [0003] Existing baking furnaces, such as a ferroalloy baking furnace disclosed in utility model CN201637263U, ...

AI Technical Summary

Problems solved by technology

[0007] The baking oven is equipped with multi-layer roasters, which improves the uniformity of the roasting temperature, but also increases the manufacturing cost of the roaster

Since the upper part of the multi-layer roaster is closer to the exhaust port, the heated flue gas of the roaster has been discharged from the exhaust port before it completely transfers heat to the alloy, which reduces the baking temperature. The energy utilization rate of the device increases the operating cost
