Pouring makings construction standard

Pouring expect as a kind of adventitious fireproof material, be all sorts of kiln furnace such as industrial furnace all the time should have fireproof product, it is important that we reach our in the choice in industrial construction. From pouring the production of makings arrives construction each link, want to press the circuit that makes scientificly to carry out, a bit error can affect kiln furnace performance. Now, let us understand pouring expect the construction when construction is normative.
One, the examination before construction
The examination before construction should undertake strictly, include the following content
1. Clear and pouring the appearance structure of material equipment is clean
2. Of craft hole stay set


3. The whole situation of construction machines and tools, brace up pound a tool to wait have in good condition each are used
4. Anchorage firmware type, dimension, decorate reach solder quality, anchor firmware has made the metal expand compensation processing
5. Firebrick thermal insulation has been done all round pouring makings dehydrate (glue) precautionary measures
6. Pouring of makings pack and date of production, hand-in-hand travel trial test in order to check whether invalidation
7. Construction reachs the mass of drinking water with water quality
8. Of construction craft recipe fulfil
When above examination is unqualified, construction just should handle qualification rear can continue construction, expire the material of invalidation must not be used, easy cause industrial accident and loss.


2, construction uses pattern plate
Usable armor plate or hard board (bamboo clappers) make. Pattern plate should have enough strength, tigidity is good, do not go form, not shift, do not leak oar. Steel pattern plate should use the agent that eliminate a model, wooden pattern plate should brush waterproof paint. Repeat use board to want to clean reuse first.
3, pouring makings liner construction
1, pouring makings construction
A, pouring feed mix
Agitate time should not less than 5 minutes. Should use when the operation forced mixer, should work first when agitate mix, rejoin 80% dissolvent agitate, inspect dry wet degree and the requirement that impose tool body place next, join odd dissolvent stage by stage again, until obtain appropriate working consistency till. Below the premise that assures construction function, dissolve dosage appropriate is little had better.
Pouring makings should use whole bags, agitate is good pouring makings is gone inside 30 minutes. Even right amount in the work environment with dry high temperature shorten time. What had coagulated first or agglomerate is pouring makings must not use, also must not add solvent agitate reoccupy.


B, brace up pound
Pouring makings use oscillator instantly into pattern plate a person operating from within in coordination with outside forces statified brace up solid, every height is less than 300mm, oscillatory span with 2500mm advisable. Avoid to touch as far as possible when vibration anchorage firmware, must not injure thermal insulation, must not be in same position is long brace up and heavy brace up. Pouring after makings surface returns an oar, answer oscillator slow take out, avoid pouring phenomenon of makings generation separation and appear empty.
Pouring after finishing pouring body is in caky before cannot again press press and get shock.
C, pouring quantity and expand seam
A construction should be divided when large area construction is pouring, every pouring area area with 1.5m2 advisable (measure synchronism with agitate) . Expand seam stay by the requirement set (be in commonly pouring when synchronous consideration) , must not omit. In kiln, decompose furnace inside expand seam set on annular circle axial, not less than 4, it is material with felt of cotton of siliceous aluminous fiber.
D, conserve and drawing of patterns are checked
Wait for pouring the conserve that asks to undertake according to construction conserve after makings surface is dry, what need water conserve especially is pouring makings, fixed aspersion, maintain its the surface is wet. Pouring expect to edge model can be demolished to continue after coagulating eventually aspersion conserve, but bearing pattern plate must wait for intensity to amount to 70% rear but drawing of patterns.
After pattern plate is demolished, answer to be opposite in time pouring body examination, discovery beehive, flake and empty wait for quality problem to want seasonable processing and repair. Should go to blemish place authentic when the problem is serious, show anchorage firmware, the tamp makings with coessential reoccupy is filled solid continue conserve. Prohibit be being wiped with slop smooth cover an issue.


2, compound liner construction
Compound to fireproof heat insolation liner wants statified section construction, forbidden mix a construction that mix an oar, heat-insulating material (like silicon calcareous plate, silicon aluminium board, asbestine or mineral wool) should besmear gush is waterproof and moistureproof material.
We are mastering pouring after makings construction standard, can coach construction group undertakes the project works efficiently. Can improve work efficiency already so, in the meantime, we also can avoid occurrence mistake to operate through reasonable standard, waste material, appear to later period even the circumstance of industrial accident.
