Description
Art
The invention belongs to heating furnace thermal processing equipment field.
Background technology
In machine-building processing industry, often need workpiece is carried out local heat treatmet or Fractional Heat-treatment.Heat exchanger is along with the fast development of refinery and coal chemical industry, structure also becomes increasingly complex, especially the many changes of structure of tube sheet and tube bank process to sweating heat and bring very big inconvenience, Fractional Heat-treatment and tube head and divide local heat treatmet to be one of important measures solving problems in manufacture process.
At present, the method that Fractional Heat-treatment and local heat treatmet are commonly used is the electrically heated method in heat-preservation cotton blocking fire door gap or local.Heat-preservation cotton blocking fire door gap thermal insulation weak effect, is extremely difficult to the temperature of technological requirement near fire door, heat dissipation capacity is big, causes mass energy to waste.Local electric heating heating power is relatively low, it is impossible to effectively paste workpiece, and conduction of heat thermograde is big, and thermal effectiveness is poor, is even unable to reach technological requirement；Heat conducting and radiating amount is big, and capacity usage ratio is low.
Summary of the invention
The problem that we to solve is: overcome prior art defect, improves fire door position thermal insulation effect, to meet the needs of multiclass workpiece and technique.
The invention provides a kind of fire door auxiliary mould, its structure has: panel 1, hanger 2, arc plate 3, cat ladder 4, bearing rib 5, reinforcement plate 6, main frame 7, fixing gusset 8, refractory fibre heat insulating block 9；Wherein panel 1 is welded on main frame 7 outer surface, and on panel 1, left and right is symmetrically welded hanger 2, cat ladder 4, bearing rib 5, strengthens plate 6；Arc plate 3 is positioned at panel 1 central authorities, opening upwards；Refractory fibre heat insulating block 9 is put in main frame 7, and fixing gusset 8 reinforces main frame 7.
Its using method is: the bottom of described main frame 7 is sitting in former heating-furnace car front-end platform, and the top of main frame 7 is relied on weight compression by former fire door；Described panel 1 both sides are compressed fire door auxiliary mould by former door side sealing cylinder device；Described arc plate 3 aperture position is the gateway of workpiece, seals by refractory fibre heat-preservation cotton between workpiece and arc plate 3.
The invention has the beneficial effects as follows, solve fire door spot temperature on the low side, the problem that furnace temperature is uneven, ensure that burner hearth temperature uniformity, furnace treatment reason and Fractional Heat-treatment work are entered in the local that can be effectively taking place multiclass workpiece, greatly extend the function of original heat treatment heating furnace, improve local heat treatmet effect, improve the quality of product；Improve the utilization rate of the energy, reduce production cost.
This fire door auxiliary mould, simple to operate, easy for installation, and, do not affect the use of original fire door, do not destroy the structure of former heat treatment heating furnace.

Detailed description of the invention
As shown in drawings, the invention provides a kind of fire door auxiliary mould, its structure has: panel 1, hanger 2, arc plate 3, cat ladder 4, bearing rib 5, reinforcement plate 6, main frame 7, fixing gusset 8, refractory fibre heat insulating block 9；Wherein panel 1 is welded on main frame 7 outer surface, and on panel 1, left and right is symmetrically welded hanger 2, cat ladder 4, bearing rib 5, strengthens plate 6；Arc plate 3 is positioned at panel 1 central authorities, opening upwards；It is internal that refractory fibre heat insulating block 9 puts main frame 7, and fixing gusset 8 reinforces main frame 7.
Its using method is: the bottom of described main frame 7 is sitting in former heating-furnace car front-end platform, and the top of main frame 7 is relied on weight compression by former fire door；Described panel 1 both sides are compressed fire door auxiliary mould by former door side sealing cylinder device；Described arc plate 3 aperture position is the gateway of workpiece, seals by refractory fibre heat-preservation cotton between workpiece and arc plate 3.
This fire door auxiliary mould uses program as follows:
(1) original Compaction of Heating Furnace Door is fully opened, until maximum height, and avoid colliding with；
(2) lifting tool is fixed on hanger 2, utilizes lifting tool that fire door auxiliary mould is winched to heating furnace place；
(3) bottom of main frame 7 must rest easily within stove car front-end platform, adjusts fire door auxiliary mould and arrives former fire door position；
(4) open former Compaction of Heating Furnace Door, make fire door move down, use the top of former door weight compression fire door auxiliary mould main frame 7；
(5) former heating furnace side seal air cylinder device, closed furnace door auxiliary mould are opened；
(6) light a fire according to furnace operation code；
(7) heat exchanger tube tube head end or need the reactor shell of Fractional Heat-treatment to enter in stove by fire door auxiliary mould upper curved plate opening, seals workpiece and arc plate 3, performs Technology for Heating Processing；
(8), after tube bank or reactor complete heat treatment, remove from arc plate opening.Unclamp heating furnace side seal air cylinder device, open former Compaction of Heating Furnace Door to maximum height, utilize lifting tool that fire door auxiliary mould is winched to deposit position.
