Description
Technical field
The invention belongs to non-ferrous metallurgy technology field, especially relate to a kind of Ausmelt furnace spray gun point
The method of fire.
Background technology
Ausmelt furnace be the exploitation of Australia Si Maite company limited of Australia for copper smelting, lead, stannum and slag
The patented technology device of fuming etc., owing to it has small investment, simple to operate, it is easy to Automated condtrol, raw
Production capacity power is big, pollutes few, flue gas can antacid and power consumption low, this special stove refractory material length in service life etc. of Australia
Feature, meets the direction of Metallurgical Industry stove development very much.
Nickel smelter at Ausmelt furnace running-in period, change spray gun or because a variety of causes such as fault cause
Exceeding half an hour down time, furnace temperature will decline, and Ausmelt furnace can be become cold conditions from hot.Due to
The chain restriction of Ausmelt furnace PCS (person-to-person communication service) control system, Ausmelt furnace is under cold conditions
Time spray gun cannot work.It is to need to carry out baker with standby burner according to the method for rule of operation igniting, carries
High furnace temperature, after nearly half an hour, Ausmelt furnace is become again hot by cold conditions, and spray gun just can normally work.Baker
This process produce impact, always have following some:
(1) consume a large amount of light diesel fuel, add production cost.
(2) reduce the Ausmelt furnace normal production time, destroy stove stability, reduce production efficiency.
(3), when using standby burner, the flue gas of generation can not be recycled, and causes environmental pollution,
It is unfavorable for the protection of environment.
(4) preparation using standby burner is loaded down with trivial details, adds the amount of labour of field worker.
(5) frequently using due to standby burner, causes standby burner malfunctions to occur frequently, shortens it and make
With the life-span, add again the waste of time cost and manpower and materials simultaneously.
Therefore need badly in the middle of prior art and want a kind of novel technical scheme to solve this problem.
Summary of the invention
The technical problem to be solved is: provide a kind of method that Ausmelt furnace spray gun is lighted a fire, and uses
Solve Ausmelt furnace from hot become cold conditions after need to carry out baker with standby burner, improve furnace temperature,
Spray gun could normally work, and can consume a large amount of light diesel fuel during baker, adds production cost, waste
Human and material resources energetically, decreases the normal production time of Ausmelt furnace, reduces production efficiency
Etc. technical problem.
The method of a kind of Ausmelt furnace spray gun igniting, is characterized in that:
