Evaporated cooling system of heat accumulating type rod and wire stepping furnace

Abstract

The invention provides an evaporated cooling system of a heat accumulating type rod and wire stepping furnace. The evaporated cooling system comprises a steam pocket, a circulating water pump water inlet header, a circulating water pump water outlet header, four sets of fixed beam cooling loops and three sets of movable beam cooling loops, wherein the four sets of fixed beam cooling loops and the three sets of movable beam cooling loops are connected with the circulating water pump water outlet header. The movable beam cooling loops comprise two loops formed by three sections of movable supporting beams and one loop formed by two sections of movable supporting beams, and the fixed beam cooling loops comprise two loops formed by three sections of fixed supporting beams and two loops formed by two sections of fixed supporting beams. The evaporated cooling system is an improvement of an existing evaporated cooling system of the heat accumulating type rod and wire stepping furnace, through the system optimizing procedure, equipment investment of a furnace bottom circulating system and the installed capacity of the evaporated cooling circulating system are reduced, and power consumption of an industry is reduced.

Description

technical field [0001] The invention relates to a heating furnace, in particular to a vaporization cooling system for a regenerative rod and wire walking furnace. Background technique [0002] At present, my country is a country with a large steel output, and steel production enterprises are large energy consumers and emitters. Saving and reducing emissions is not only an inevitable requirement for sustainable social development, but also plays a significant role in reducing costs and improving efficiency for enterprises. Evaporation cooling technology has been used in pusher heating furnaces since the 1960s. In the middle and late 1990s, walking beam heating furnace vaporization cooling technology began to be used. After years of design and use, a lot of experience has been accumulated. Due to the continuous increase of fuel costs, the regenerative combustion technology makes full use of the low calorific value fuel blast furnace gas, and the regenerative heating furnace ha...

Problems solved by technology

The actual operating flow rate is much higher than the critical flow rate. Although the cooling effect of the water beam can be guaranteed, the circuit resistance increases and the circulation flow of the system increases, which leads to an increase in the head of the circulation pump, an increase in the flow rate, and an increase in the power of the equipment. The system input cost and operating cost are correspondingly higher
