Embodiment Construction
[0041] The embodiment of the present application provides a roller hearth tunnel heating furnace, which solves or partially solves the technical problems in the prior art that the heating furnace is long, and there is a risk of casting slab deviation or even bumping out of the furnace wall. By setting the furnace body, The roller hearth tunnel heating furnace composed of multiple burners, sealing devices, the first automatic flame cutting gun and the second automatic flame cutting gun can significantly shorten the length of the heating furnace and greatly reduce the cost of casting slab while ensuring the heating effect. The probability of deviation in the furnace significantly reduces the technical effect of equipment cost.
[0042] See attached figure 1 and 2 , The application provides a roller hearth tunnel heating furnace, including: a furnace body, a plurality of burners, a sealing device 7, a first automatic flame cutting gun 3 and a second automatic flame cutting gun 4...
