Problems solved by technology

[0002] Most of the existing melting furnaces, especially steel melting furnaces, are melted in coking furnaces. Coking furnaces melt metal materials, which have low thermal efficiency and pollute the environment. Generally, one ton of cast iron is melted. It needs 0.35 tons of coke, the current market price is about 1000 yuan, the melting cost is high, and the melting cycle is long

Embodiment 2

[0042] For the main view of this embodiment, see figure 1 , Its structure see Figure 14 versus Figure 15 In this embodiment, the length of the molten pool is 3m, the width is 3m, and the depth is 1m. The capacity is 20 tons when melting cast iron. The difference between this embodiment and the first embodiment is that a furnace body 73 is provided with two heat storage heat exchangers 14 with the same structure. Each heat storage heat exchanger 14 is equipped with an exhaust fan 3, an exhaust pipe 4, and a pipe. Connector 5, vent valve 6, steering gear 7, vent pipe 8, vent pipe 24, intake pipe 9, blower 10, nozzle gas heater 11, gas pipe 12, valve 13, valve 27, blower 22 and high pressure gas pipe 25, An air compressor 28 supplies compressed air to the two high-pressure gas pipes 22, and a set of gas cylinders supplies gas to the two gas pipes 12. There are four furnace body ventilating pipes 40 and furnace body ventilating pipes 41 in the furnace 78.

Abstract

The invention relates to a melting furnace. The melting furnace consists of a furnace body, a nozzle combustion heater and a regenerative heat exchanger, wherein, the nozzle combustion heater is arranged in a slanted way at the bulkhead of the furnace body and faces a melting bath. The nozzle combustion heater consists of a high internal pressure gas pipe, a gas pipe and the vent sleeve, wherein, the high internal pressure gas pipe and the gas pipe are sheathed in the vent sleeve. The regenerative heat exchanger is provided with a ventilation device. The melting furnace has the advantages of high thermal efficiency utilization rate, and short melting cycle.

Description

technical field [0001] The invention relates to a melting furnace. Background technique [0002] Most of the existing melting furnaces, especially steel melting furnaces, are melted by coking furnaces. Coking furnaces melt metal materials, which have low thermal efficiency and pollute the environment. Generally, 0.35 tons of coke is needed to melt one ton of cast iron. The current market price is about 1,000 yuan, and the melting cost High, long melting cycle. Some are melted with an electric furnace, which consumes a lot of electricity. Melting a ton of cast iron consumes about 1,000 degrees of electricity, and the current market price is about 500 yuan. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the existing melting furnace, the present invention provides a gas-fired melting furnace, which can be used to melt metal raw materials or metal ores, and the cost of heating and melting is low. [0004] The present invention ...
