Batching process of ramming mass/refractory concrete
The ingredient is according to the process requirements will be a good polishing of all kinds of raw materials according to the ratio of mixing, and the unity of raw materials according to a certain particle synthesis of mixed operation process,chemical synthesis and particle synthesis.With the functional requirements of products, the properties of raw materials used and the process of adjustment. refractory concrete
Chemical synthesis
 Chemical synthesis must meet the requirements of products, and should be higher than the index requirements of products.This is due to the balance to the raw materials and products of chemical synthesis may be erratic, there may be errors in sample analysis.Which contains the content of important ingredients, provision permits fusible and harmful impurities of total impurities.
At present, it is widely quoted by semi dry process, which requires that the blank should have enough conclusion, so it should be included in the ingredients.Binding by the main ingredients to bear, if the main raw material is poor, the conclusion has ability to complete bonding agent.Such as paper pulp waste liquid, the conclusion of clay and lime milk, etc.
In addition to the physical function of the blank, the paper will not affect the chemical composition of the products, and the conclusion of clay and lime milk will have a remarkable influence on the chemical synthesis and the function of the products.
The ingredients, sometimes articles according to functional requirements, also need to add some other objects. Such as yielding high porosity products, added sawdust, sawdust charcoal or other combustible materials, in order to make the product more stomata.refractory concrete
Granular synthesis
The blank particles synthesized have very very big influence on density of green body. In the premise of not weigh themselves under the shape of particles, the total aggregate made from narrow body powder, equal original pore volume.
Therefore, it is possible to obtain compact bodies only if the particles are synthesized by the close packing theorem.In accordance with the mouth of steady dense packing theorem, which makes the ideal granular synthesis of coarse particles formed between the particles formed in the frame, add large particles and large particles like tangent fine powder complement between particles and large particles of loopholes, and the ideal static like this, in the actual production process is how to achieve.Due to the small size of the particles are often concentrated in large particles, and very very little free movement. So no sensation or oppression, are difficult to adjust such a static and achieve the ideal situation,Even if the introduction of smaller particles, the situation is no way. Although this, after theoretical measurement and testing, can still draw the following conclusions have practical significance:

1. Reference single particles can not achieve a close stack.
2. Reference multicomponent particles can reach close packed, and the components and proportion of particles is bigger better. Normal is 4 ~ 5 times more effective.
3. The number of very fine particles, the gap should constitute a sufficient supplement in the close scheduling. The number of particles lies in the particle shape and supplement.In fact, when there are two kinds of particles, the ratio of the number of coarse particles to 7:3, when there are three kinds of particles when the particle is 7:1:2.
4. The growth in the number of particulate components can stimulate the packing density, making it close to the mouth of steady dense packing components, but when more than 3, little practical significance.
5. In the possible premise, the critical particle proportion should be appropriately increased to expand the proportion of the proportion of the proportion of each component.

In the production of refractory materials refractory concrete, usually more than three kinds of components to adopt a tacit understanding.But their particle size range is not uniform.In fact, it is affected by the raw material of the cannon and other premise of the impact is difficult to fixed.
As the particle size range can be ascertained:
Thin particles: 0 to 0.2mm (or 0.1mm);
Medium grain: 0.2 (0.1) mm ~ 0.5mm;
