Description
Technical field
The utility model belongs to smelting iron and steel technical field, further belongs to roaster technical field, is specifically related to a kind of simple in structurely, and gas-fired is abundant, reliable operation, the easy for installation clean-burning hot-metal bottle roaster of blast furnace gas that contributes to.
Background technology
Heat-storage ladle roaster is for toasting a kind of device of ladle, general steel ladle after new block and splendid attire molten steel all need to toast as last, so ladle baking facility plays vital effect.What heat-storage ladle roaster adopted is a kind of very effectively flue gas waste heat recovery regenerative combustion technology, replaces switch operating carry out the waste heat in recovered flue gas in heat absorption and release state by paired heat storage.
In actual use, when roaster is directly used blast furnace gas, gas pressure is easily subject to the impact of workshop blast-furnace gas pressure output size and regenerator filling heat-storing material amount, while making gas-fired, occur that flame is little, the problems such as flame rigidity is not strong, have a strong impact on iron flask baking quality, and easily stop working and easily cause blast furnace gas leakage to jeopardize the problems such as personal safety.
For this reason, research and develop a kind of simple in structurely, gas-fired is abundant, reliable operation, and the easy for installation clean-burning hot-metal bottle roaster of blast furnace gas that contributes to, is with a wide range of applications.
Utility model content
It is a kind of simple in structure that the purpose of this utility model is to provide, and gas-fired contributes to the clean-burning hot-metal bottle roaster of blast furnace gas fully.
The purpose of this utility model is achieved in that and comprises gas pipe, roaster end cap and baking body; Described gas pipe is connected with roaster end cap; Roaster end cap comprises cover plate, ring gas pipeline, end cover body, bracing frame and gas port, and described ring gas pipeline is arranged in end cover body by bracing frame, and is connected with gas port with gas pipe respectively; Described cover plate coordinates the interior chamber that forms a sealing with end cover body; Described gas port passes cover plate and is fastened thereon.
The utility model adopts roaster end cap and ring gas pipeline fit structure, in the situation that guaranteeing that gas pressure is constant, realized and utilized in tank and cover heat carries out the function of preheating to blast furnace gas and forced air, made the more inflammable and sufficient combustion of blast furnace gas.According to statistics, in first 2012 whole year of transformation, slag iron workshop consumes mixed gas 4185.747km3 altogether, 3332432.25 yuan of generation expenses, and average single tank consumes mixed gas 3.229 km3, roasting tank expense 2652.66 Yuan ∕ Guan ﹙ 821.51 Yuan ∕ m3 ﹚.After roasting tank arrangement transformation, the gas consumption that toasts single new tank is 2040 yuan, than the roasting tank expense of 2012 annual list tanks, reduces approximately 600 Yuan ∕ tanks.The utility model is simple in structure, and gas-fired is abundant, and reliable operation is easy for installation.
