Description
Technical field
The present invention relates to a kind of feeding track device of pusher type furnace.
Background technology
In general pusher type furnace mainly is used for handling large-scale aluminium block or large-scale alloy aluminium block, and this type aluminium block can weigh several tons.This type of pusher type furnace normally pushes aluminium block through the stove section by the hydraulic pressure puopulsion equipment.Generally when propelling is initial, need a tripping force.This initial start power must be able to let the slide block that is loaded with weight on slide rail, move steadily.
Aluminium block by output and be loaded into and be to accomplish synchronously that its rhythm is decided by rolling rhythm.According to the varying in size of heat-treatment furnace, the size of furnace charge and the rolling rhythm that the quantity difference has determined this stove is 2 to 4 hours; Heat treatment time can be between 6 to 18 hours; Aluminium block remains on the static position up to being drawn out the stove section from being urged in the stove, and these aluminium blocks will be spent between 610 degree 470 according to the requirement of its alloy and heat-treated.Equipment for Heating Processing is with combustion vapour or fuel heater heating, and heat energy carries out the advection heat conduction through blower fan system.
When the slide rail that is arranged in stove and slide block are advancing and heat treated process, tend to owing to (similar welding) phenomenon that bonds occurs between slide block that long-time soak causes and the slide rail, thereby have influence on the normal slip of slide block, cause fault.
Summary of the invention
The object of the present invention is to provide a kind of feeding track device of pusher type furnace.
In order to reach above purpose, the scheme that the present invention adopts is:
A kind of feeding track device of pusher type furnace; Comprise: run through body of heater and the slide rail that laterally arranges, be arranged on the slide block that described slide rail upper end is used for the carrying furnace charge, it is characterized in that: described slide rail is selected the Cr of the material preparation of following composition: 17.0%-19.0%, the Ni of 8.0%-10.0%, the Si of 1.0%-2.0%, the Mn of 0.5%-1.5%, C and the Fe of 0.15%-0.5% for use; Described slide block is then selected following composition preparation for use: the Cr of 6.0%-8.0%, the C of 0.2%-0.4% and Fe; On described slide rail, also be provided with lubrication unit; This lubrication unit comprises the proportioner that is used to carry at least one lubrication hole of lubricating grease and the lubricating grease of providing and delivering; Described lubrication hole is arranged on the slide rail of body of heater inlet; Described proportioner is connected with described lubrication hole; When described slide block entered the mouth through body of heater, described proportioner was thrown a lubricating grease in the slit between described slide rail and the slide block into through described lubrication hole, and described slide block is distributed to this part lubricating grease on the whole width of the described slide rail of correspondent section when motion equably.
In above-mentioned technical scheme, the quota of preferred described lubricating grease is according to the requirement dispensing that is the 0.1-0.5 cubic centimetre of every meter furnace superintendent, and further the quota of preferred described lubricating grease is 0.3 side's centimetre requirement dispensing according to every meter furnace superintendent.
In addition, preferred described lubricating grease by grease and carbon (graphite) by 10: 1-100: 1 mixed forms.
The present invention compared with prior art has following advantage: the slide rail of material preparation of the present invention and wearability, the heat-resisting quantity of slide block are high relatively, and lubrication unit also can make the frictional force between slide block and slide rail be reduced to minimum simultaneously.

The specific embodiment
Describe concrete structure of the present invention below with reference to accompanying drawings in detail:
A kind of feeding track device of pusher type furnace comprises: run through heat insulation body of heater 1 and the slide rail 5 that laterally arranges, be arranged on the slide block 6 that slide rail 5 upper ends are used for the carrying furnace charge.Shown in accompanying drawing 1: pending aluminium block 7 is placed on the slide block 6 and through slide rail 5 and is admitted in the heat insulation body of heater 1, in heat insulation body of heater 1, is provided with the coupled water conservancy diversion internal portioning layer 4 that passes through, and the aluminium block 7 that is placed on the slide block 6 passes through from water conservancy diversion internal portioning layer 4.Heat insulation body of heater 1 is provided with heater 2, and heat energy carries out advection heat conduction through blower fan 3, and this blower fan 3 is connected with water conservancy diversion internal portioning layer 4.Heater 2 heats gas through employing combustion vapour or fuel oil and imports in the heat insulation body of heater 1, and heat energy is heat-treated through getting into 4 pairs of aluminium blocks 7 of water conservancy diversion internal portioning layer.
Because aluminium block 7 needs long soak in heat treatment process; Slide block 6 that causes easily and the bonding between the slide rail 5 (similar welding) phenomenon; Therefore must consider when selecting the combination of materials of slide rail 5 and slide block 6 that two kinds of materials are non-caked each other under long-time high temperature inactive state; And the ability wearability is high relatively under motion state, and the frictional force that while slide block 6 and slide rail are 5 can be reduced to minimum again.The slide rail 5 of present embodiment is selected the Cr of the material preparation of following composition: 17.0%-19.0%, the Ni of 8.0%-10.0%, the Si of 1.0%-2.0%, the Mn of 0.5%-1.5%, C and the Fe of 0.15%-0.5% for use; 6 of slide blocks are selected following composition preparation for use: the Cr of 6.0%-8.0%, the C of 0.2%-0.4% and Fe.The slide block 6 of the preparation of this type of material and slide rail 5 are high temperature resistant and wearability good.
Simultaneously, for solving the frictional force problem of 5 of slide block 6 and slide rails, also be provided with lubrication unit on the slide rail 5; Shown in accompanying drawing 2; This lubrication unit comprises the proportioner of at least one lubrication hole 8 of carrying lubricating grease 9 and the lubricating grease 9 of providing and delivering, and is also not shown in the accompanying drawing, and lubrication hole 8 is arranged on the slide rail 5 of heat insulation body of heater 1 inlet; Proportioner is connected with lubrication hole 5; When slide block 6 passed through the inlet of heat insulation body of heater 1, proportioner was thrown a lubricating grease 9 in the slit between slide rail 5 and the slide block 6 into through lubrication hole 8, when slide block 6 is distributed to this part lubricating grease 9 on the whole width of correspondent section slide rail 5 when moving equably.
In addition lubricating grease 9 by grease and carbon (graphite) by 10: 1-100: 1 mixed forms.Usually the quota of lubricating grease 9 is the requirement dispensing of 0.1-0.5 cubic centimetre according to every meter furnace superintendent, and every meter furnace superintendent is that 0.3 side centimetre then is optimal way.
