Embodiment Construction

[0017] Such as figure 1 and figure 2 As shown, a tube-type water-cooling device for casting furnace roof lining is provided with a water-cooled tube 1 for cooling water circulation and an outer sleeve 2 wrapped outside the water-cooled tube 1, and the water-cooled tube 1 and The outer casing 2 is buried in the refractory lining 8 on the top of the casting furnace. The outer diameter of the water-cooled pipe 1 and the inner diameter of the outer casing 2 are set so that the water-cooled pipe 1 can slide and extend along the outer casing 2 when heated and expanded. Both ends protrude from the refractory lining 8, and the two ends of the water-cooled pipe 1 protruding from the refractory lining 8 are respectively equipped with valves for controlling water inlet and outlet; the upper side of the outer casing 2 is provided with an opening extending along its axial direction. The opening is exposed to the outside of the refractory lining 8, and the arc length of the opening on the...

Abstract

Disclosed is a tube-type water-cooling device used for a top lining of an integral casting furnace. The tube-type water-cooling device provided with a water-cooling tube used for circulation of cooling water and an outer sleeve sleeving the outside of the water-cooling tube, both the water-cooling tube and the outer sleeve are embedded in the refractory furnace lining at the top of the integral casting furnace, the arrangement of the size of the outer diameter of the water-cooling tube and the inner diameter of the outer sleeve enables the water-cooling tube to extend in sliding along the outer sleeve when the water-cooling tube is heated to expand, and two ends of the water-cooling tube extend out from the refractory furnace lining. When heated to expand and blown out to cool, the water-cooling tube can extend or retract freely and axially to two ends along the outer sleeve, the water-cooling tube is protected to be used safely and the cooling water is prevented from leaking, and potential safety hazards of leakage inside the furnace is solved; the water-cooling device is simple in material using and manufacturing, low in manufacturing cost, high in cooling efficiency and applicable to various furnace types.

Description

technical field [0001] The invention relates to a cooling device for furnace lining of smelting and chemical heat equipment, in particular to a tube-type water cooling device for pouring furnace top furnace lining. Background technique [0002] Due to the development of smelting and chemical technology and the needs of energy saving and environmental protection, the furnace type of smelting and chemical heating equipment is getting larger and larger, and the shape of the furnace roof is more complicated. As a result, the span of the roof lining structure is also increasing, and the stability and strength of the furnace roof lining are challenged. However, the modern smelting process is more complicated and changeable, the smelting reaction intensity is more intense, and the temperature is higher, which has a greater impact on the thermal shock of the furnace roof lining. The furnace roof lining of thermal equipment becomes one of the areas most vulnerable to damage and loss...
