Abstract
The utility model discloses a steel rolling heating furnace with double slideways. The steel rolling heating furnace is provided with two groups of slideways, wherein each group of slideways comprises sliding rails, supports and steel pushing bars, the sliding rails are fixed on the supports which are fixed at the bottom of a hearth, and the steel pushing bars are movably arranged in grooves in the upper parts of the sliding rails. When the steel rolling heating furnace with the double slideways is used, a feeder moves steel billets put on the steel pushing bars at intervals to the hearth by pushing the steel pushing bars, the steel billets are heated to preset temperature and then are pushed out of the heating furnace, and after the steel pushing bars drop out from a steel pushing bar outlet and are cooled, the steel pushing bars are fed into the sliding rail grooves at a steel billet inlet. The steel rolling heating furnace with the double slideways has the advantages that as the two groups of slideways are arranged in the hearth, two rows of steel billets can be simultaneously heated once, so that the consumption of energy sources is reduced, and the production efficiency is improved; an interval is reserved between the two steel billets, so that when the steel billets are heated to high temperature, the steel billets do not bulge and deform, the steel billets are uniformly heated in the hearth, and temperature difference black imprints do not occur.
Description
Technical field
The utility model relates to a kind of heater for rolling steel, is specifically related to a kind of pair of slideway heater for rolling steel.
Background technology
Heater for rolling steel is the main heating installation of Metallurgical Enterprise, its effect be by heating steel billet to the temperature that is easy to rolling, the heating quality of process furnace directly has influence on the quality of steel rolling product performance and the height of production cost.Pusher-type furnace is a kind of metallurgical industrial furnace widely using in medium and small Metallurgical Enterprise process furnace, being arranged on slideway in burner hearth and being and in process furnace, be used for the parts that support is heated steel billet and directly contacts with steel billet, is the principal element that determines process furnace billet heating temperature homogeneity, energy consumption level and auxiliary facility working cost.
The slideway of existing pusher-type furnace is generally that two one slide rail levels are laid on to burner hearth bottom, and the distance between two one slide rails is depending on being heated the length of steel billet, and the surface of slide rail is plane, and wider with the contact surface of steel billet.In heating steel billet process, feeder will be heated steel billet and send into slideway, and steel billet is pushed ahead, its impetus is in a side of steel billet, be heated one, steel billet and connect one and move in burner hearth along slideway, be pushed out process furnace after being heated to preset temperature, enter rolling shedule.Although this pusher-type furnace is simple in structure, there is following shortcoming: 1. because the gap being heated between two, steel billet is little, while being heated to high temperature, easy arch camber distortion, causes the movement of steel billet to stop, and what impact was produced normally carries out.2. because the gap being heated between two, steel billet is little, and wider with the contact surface of slideway, cause heating steel billet inhomogeneous, easily produce the black seal of the temperature difference.3. the slideway of being laid by two one slide rail levels in burner hearth once can only heat a row steel billet, causes production efficiency not high.
Summary of the invention
The purpose of this utility model is to overcome prior art deficiency, and a kind of two row steel billets that once can heat are provided, and saving energy, production efficiency are high, and can arch camber distortion, homogeneous heating, can effectively solve a kind of pair of slideway heater for rolling steel of the black seal problem of the temperature difference.
The purpose of this utility model is achieved in that a kind of pair of slideway heater for rolling steel, comprise body of heater, burner hearth, be arranged on the steel billet import of body of heater one end, the steel billet of a side exports and be arranged on the slideway of burner hearth, it is characterized in that: described slideway is two groups even, to be horizontally set on burner hearth middle and lower part.
Described slideway comprises slide rail, support and pushes away rod iron, and slide rail is fixedly installed on support, and support is fixedly installed on burner hearth bottom, pushes away in the groove that rod iron is movably arranged on slide rail top.
The described rod iron that pushes away is N joint, and the length that every joint pushes away rod iron is 250～280mm, and diameter is 80～100mm.
The other end of described body of heater is provided with and pushes away rod iron outlet.
In the utility model when work,, be heated steel billet interval and be placed in and push away on rod iron, and feeder pushes away rod iron by promotion, interval is placed in to the steel billet pushing away on rod iron and is transferred in burner hearth, is pushed out process furnace after being heated to predetermined temperature, enters rolling shedule.Steel billet after heating is pushed out after burner hearth, pushes away rod iron and continues to drop out from pushing away rod iron outlet along the groove of furnace bottom, sends in the sliding rail groove of steel billet ingress after cooling again.
Compared with prior art, the utility model has the advantages that:
1, saving energy, production efficiency are high.The utility model is provided with two groups of slideways in burner hearth, once can heat two row steel billets simultaneously, has greatly saved energy consumption, has improved production efficiency, has reduced production cost.
2, can arch camber distortion, homogeneous heating.Because the utility model is fixedly installed slide rail on slideway, in the groove on slide rail top, be movably set with N joint and push away rod iron, being heated steel billet interval is placed in and pushes away on rod iron, with the contact surface that the pushes away rod iron top for pushing away rod iron cambered surface only, the impetus of feeder is pushing away a side of rod iron, feeder pushes away rod iron by promotion, interval is placed in to the steel billet pushing away on rod iron to be transferred in burner hearth, be heated and between steel billet, leave interval due to two, while being heated to high temperature, can arch camber not be out of shape, guaranteed normally carrying out of production, be heated steel billet narrower with the contact surface that pushes away rod iron simultaneously, in addition between two blocks of steel billets, leave interval, make to be added steel billet is heated uniformly in burner hearth, can not produce the black seal of the temperature difference.
