Description
Technical field
The utility model relates to special metallurgical transport vehicle field, particularly a kind of hot-metal insulating car.
Background technology
Hot-metal ladle and carriage be smelter with molten state blast-meltedly be transported to that steel mill, pig machine, Foundry Works are made steel, the special-purpose vehicle of casting pig or teeming mould etc., mostly the hot-metal bottle on the vehicle frame is uncovered, because transportation range is longer relatively; Thermal loss is still bigger in transit; The molten iron band quantity of slag increases, and has both reduced the recovery rate of molten iron, influences the service efficiency of hot-metal bottle again; Shorten the hot-metal bottle life-span; Therefore change the structure of conventional iron water-tank lorry, improve its heat-insulating property, be of great immediate significance addressing the above problem.
Summary of the invention
The purpose of the utility model provides a kind of hot-metal insulating car, overcomes the deficiency of prior art, on common hot-metal ladle and carriage, installs attemperator additional; The heat that reduces in the hot-metal bottle transportation scatters and disappears; Reduce temperature drop, reduce the molten iron band quantity of slag, improve hot-metal bottle service efficiency and life-span.
For solving the problems of the technologies described above, the technical scheme of the utility model is:
A kind of hot-metal insulating car comprises hot-metal bottle and vehicle frame, and the hot-metal bottle mouth is provided with cover; Vehicle frame is provided with the cover lift rotating equipment, and the cover lift rotating equipment is connected with cover.
Said cover lift rotating equipment comprises bracing frame, guide post, leading screw, hoisting nut, lifting motor, pivot link, rotary electric machine and fixed arm; Bracing frame one end links to each other with vehicle frame; The other end of bracing frame vertically is provided with guide post; The leading screw two ends are connected respectively with between the guide post, and hoisting nut is connected with threads of lead screw respectively and guide post is slidingly connected, and lifting motor is located at an end of leading screw;
One side of hoisting nut is provided with swinging mounting, and an end of pivot link links to each other with swinging mounting, and the other end of pivot link links to each other with an end of fixed arm, and the other end level of fixed arm is provided with cover, and an end of pivot link is provided with rotary electric machine.
The effective length of said leading screw is more than or equal to 500mm.
Compared with prior art, the beneficial effect of the utility model is:
1) hot metal temperature drop speed is reduced to 0.4 ℃/min by original 0.9 ℃/min, and when transporting to, molten iron temperature is brought up to 1375 ℃ by original average 1300 ℃;
2) common uncovered jar average life span is nearly 80 stoves, ties not only after the improvement that iron alleviates but also refractory consumption rate can reduce 0.3Kg/t, and the life-span can reach more than 300 times;
3) reduce the hot metal in steelmaking band quantity of slag, improved the molten iron recovery rate;
4) improved the service efficiency of hot-metal bottle, improved hot-metal bottle turnover situation, making hot-metal car no longer only is a kind of means of transport, has more functional and sustainability.
