Abstract

The invention discloses a control method of a regenerative burner of a regenerative heating furnace The regenerative heating furnace comprises a furnace body comprising a heating section and a soaking section; an auxiliary smoke exhausting pipe is mounted on the furnace body, and regenerative burners for heating billet steel are also distributed on two sides of the furnace body; the regenerative heating furnace also comprises a four-way air reversing valve and a four-way coal gas reversing valve, which are communicated with the furnace body; and in a process of processing special steel, the regenerative burners on the two sides of the furnace body in the heating section are controlled to periodically and reversely burn, the four-way air reversing valve and the four-way coal gas reversing valve are adjusted to simultaneously convey the air and the coal gas to the two sides of the furnace body in the soaking section, the regenerative burners on the two sides of the furnace body in the soaking section are kept in an entire combustion status, and excessive smoke is exhausted through the auxiliary smoke exhausting pipe. The method disclosed by the invention can effectively avoid steel sticking and avoid local overheating and overburning of the billet steel.

Description

technical field [0001] The invention relates to the field of controlling and using the regenerative burner of a regenerative heating furnace in a steel plant, and is especially suitable for the control method of the regenerative burner of a regenerative heating furnace. Background technique [0002] At present, large iron and steel enterprises generally use advanced regenerative heating furnaces to heat billets before rolling. Regenerative combustion heating furnaces have been widely used in iron and steel enterprises since the end of the 20th century. Their main advantages are: 1. Gas with low calorific value can be used as fuel; lower fuel costs and improve market competitiveness. [0003] In order to save investment, iron and steel enterprises generally directly modify the combustion system on the old heating furnace. This modification only improves the heating capacity of the heating furnace, and cannot carry out corresponding structural design and improvement on the fu...
