Abstract
The provided cast material for large-scale cement rotary kiln has well physical and chemical performances, saves labor and material, and can improve yield.
Description
Technical field:
The present invention relates to refractory materials, specifically the present invention relates to the mould material that new dry process large-scale cement rotary kiln kilneye inside liner uses especially.
Background technology:
Fast development along with the technology of cement burning, cement rotary kiln is towards energy-conservation, the environmental protection large scale development, because the raising of kiln body rev up, make the washing away of thermal material that rotary kiln kilneye inner lining refractory is born, the erosion of highly basic gas is stronger, because the working temperature of kilneye is directly exposed in the air again, and start-stop kiln gradient of temperature is too fast, so the refractory liner at this position peels off very soon, burst, need often to repair or change, influence the normal operation of whole piece cement producing line, reduced the output of cement, also wasted the financial resources of great amount of manpower.In order to overcome the defective of above-mentioned cast, the inventor is through studying intensively, mould material each component and proportioning thereof have reasonably been selected, 65% aggregate adopts the lower special grade bauxite grog of price, matrix partly adopts fine and close fused corundom fine powder, composite additive, steel fiber electric smelting cement etc. have been finished the present invention.
Summary of the invention:
The purpose of this invention is to provide a kind of high temperature resistant, good thermal shock stability, alkaline resistance properties is good, the novel mould material of high-strength wearable, i.e. new type nonaqueous cement rotary kiln mould material.
Another object of the present invention provides described new dry process large-scale cement rotary kiln and can be used as positions such as large-scale cement rotary kiln kiln hood, coal powder injection mouth, preheater with mould material and do used for refractory material.New dry process large-scale cement rotary kiln of the present invention is made up of A and B two portions with mould material, and wherein the weight of each component is 100% in the cast gross weight:
A partly is the uniform mixture with following each component:
The special grade bauxite grog, wherein granularity 10-5mm accounts for 20-25%, and 5-3mm accounts for 10-20%, and 3-1mm accounts for 10-18%, and 1-0.5mm accounts for 15-20%;
Magnesium-aluminium spinel 1-0.5mm accounts for 3-8%;
Fine and close fused corundom fine powder accounts for 13-18% less than 0.044mm;
Steel fiber accounts for 1-3%;
Composite additive accounts for 8-12%.
B partly is that wedding agent electric smelting cement accounts for 3-8%;
Its condition be each component be combined into 100%;
This is that a preferred embodiment is:
A partly is the uniform mixture of following each component:
The special grade bauxite grog, wherein granularity 10-5mm accounts for 18%, and 5-3mm accounts for 15%, and 3-1mm accounts for 15%, and 1-0.5mm accounts for 17%;
Magnesium-aluminium spinel 1-0.5mm accounts for 5%;
Steel fiber accounts for 1%;
Fine and close fused corundom fine powder accounts for 14% less than 0.044mm;
Composite additive accounts for 10%, and wherein (silicon powder accounts for 0.50%, and STPP (sodium tripolyphosphate) accounts for 0.15%, and metallic aluminium powder accounts for 0.1%, and the magnesium-aluminium spinel micro mist accounts for 2.25%, and the electrosmelted magnesite clinker segmentation accounts for 3%, α-Alo
3Particulate accounts for 4%).
B partly is that wedding agent electric smelting cement accounts for 5%.
Each component be combined into mould material gross weight 100%.
Matrix is partly selected fine and close fused corundom fine powder, composite additive, and electric smelting cement is because this combination and aggregate avidity are strong, autoreaction, self-expanding, and the volume density height, apparent porosity is low, has good workability, and adding steel fiber just intensity increases, and thermal shock resistance is good.
Used each component is to well known to a person skilled in the art product in the mould material of the present invention, all can buy on market.
The production of mould material of the present invention, construction are to well known to a person skilled in the art technology for baking.By preferred embodiment, 2000 tons of two daily outputs in product China cement mill that we produce, just usefulness on the dry production rotary kiln end, mean lifetime has all surpassed 300 days.
