Abstract
The utility model provides a welt for bottom of high temperature box electric stove, this welt comprises bottom plate, spoke and lacing wire, and a plurality of spokes evenly arrange on the bottom plate, and both ends respectively are equipped with the lacing wire. The utility model discloses welt simple structure, reasonable in design adopts the one shot casting shaping of high temperature heat-resisting metal material, and not only high temperature resistant can prevent to warp again, has not only effectively prolonged the life of welt, reduces the equipment investment, has alleviateed intensity of labour, but also has the synchronism that does benefit to steel billet (spindle) heating.
Description
Technical field
The utility model belongs to furnace bottom liner plate technology, relates in particular to a kind of liner plate that is used for high temperature cabinet-type electric furnace furnace bottom.
Background technology
Existing high temperature cabinet-type electric furnace is not installed the furnace bottom liner plate.Be protection electric furnace furnace bottom, prolong the time between overhauls(TBO) of stove, improve its service life, people lay the steel plate of one deck different-thickness on the refractory brick of furnace bottom.Yet the steel plate of being laid through high temperature, expand with heat and contract with cold, distortion is serious, needs often to change.So both increase cost, increased labour intensity again.
The utility model content
The purpose of this utility model is to overcome existing in prior technology the problems referred to above, provides a kind of and can effectively protect high temperature cabinet-type electric furnace furnace bottom, prolongs the electric furnace life cycle, can improve the burning steel quality again, and on-deformable furnace bottom liner plate.
The utility model is achieved in that this liner plate is made up of base plate, spoke muscle and lacing wire, and some spoke muscle are evenly arranged on the base plate, and two ends respectively are provided with lacing wire.
The cross section of spoke muscle described in the utility model is an isosceles trapezoid, and its base angle is 60～85 °, and spoke muscle and spoke muscle spacing ratio are 1: 4～8; The cross section of described horizontal lacing wire is 40-50cm
2, its oblique angle is 11-15 °; Described liner plate adopts high-temperature heat-resistance metal material one-time cast-forming.
The utility model lining plate structure is simple, reasonable in design, adopt the high-temperature heat-resistance metal, the spoke muscle is an isosceles trapezoid, and two ends are provided with horizontal lacing wire, and is not only high temperature resistant but also can prevent the distortion of spoke muscle, not only effectively prolonged the service life of liner plate, reduce equipment investment, alleviated labour intensity, but also help the synchronism of steel billet (ingot) heating.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model embodiment liner plate.
Accompanying drawing 2 is the A-A view of accompanying drawing 1.
Accompanying drawing 3 is the B-B view of accompanying drawing 1.
1 is the spoke muscle among the figure, and 2 is horizontal lacing wire, and 3 is base plate.
The specific embodiment
The utility model will be further described by embodiment with reference to the accompanying drawings.
From Fig. 1～Fig. 3 as can be seen the utility model liner plate formed by spoke muscle 1, laterally lacing wire 2, base plate 3.The spoke muscle 1 of 5 even layouts and two horizontal lacing wires 2 at two ends thereof are positioned on the base plate 3, as depicted in figs. 1 and 2.The utility model embodiment liner plate adopts Cr25Ni20 high-temperature heat-resistance material, a cast molding.The cross section of the utility model spoke muscle 1 is an isosceles trapezoid, and the base angle is 60 °, and spoke muscle and spoke muscle spacing ratio are 1: 5.The cross section of this spoke muscle 1 helps improving synchronism, the frictional resistance when reducing to adorn steel with tapping of steel billet (ingot) heating, also is convenient to clear up iron scale simultaneously.For preventing the distortion of drop-bottom spoke muscle, perk, the utility model respectively is provided with horizontal lacing wire 2 at the two ends of described spoke muscle 1.The cross section of described horizontal lacing wire 2 is 40cm
2, its oblique angle is 11 °.During making, the size of liner plate should meet furnace binding thermal expansion requirement, and this also is convenient to installation and removal.
Claims (3)
1. a liner plate that is used for high temperature cabinet-type electric furnace furnace bottom is characterized in that this liner plate is made up of base plate (3), spoke muscle (1) and lacing wire (2), and some spoke muscle (1) are evenly arranged on the base plate (3), and two ends respectively are provided with lacing wire (2).
2. liner plate according to claim 1, the cross section that it is characterized in that described spoke muscle (1) is an isosceles trapezoid, and its base angle is 60～85 °, and spoke muscle and spoke muscle spacing ratio are 1: 4～8; The cross section of described horizontal lacing wire (2) is 40-50cm
2, its oblique angle is 11-15 °.
3. liner plate according to claim 1 and 2 is characterized in that described liner plate adopts high-temperature heat-resistance metal material one-time cast-forming.
