Clay refractory ramming material

Date:2017-10-16 16:03 | From:Zhengzhou Sunrise Refractory | Author:admin
Clay refractory ramming material is a manual or mechanical ramming method of construction, and through the heating of hardened unshaped refractories. There is a certain degree of matching refractory aggregate, powder, binder, admixture composition, add water or other liquid after mixing from.
 
      According to the needs of the use of various materials can be made of refractory aggregate and powder ramming material. At the same time according to the requirements of refractory aggregate materials and the use of appropriate bonding agent, some ramming without binding agent and only add a small amount of flux to promote its sintering. In the acidic ramming materials commonly used in sodium silicate, ethyl silicate and silica gel as a binder. Alkaline ramming materials use magnesium chloride and sulfate and other aqueous solutions and phosphates and their polymers as binders.
 
      Clay refractory ramming material is usually used mainly with the melt in contact with the site, requiring refractories must have a good volume stability, compact and corrosion resistance, so the general use of high temperature firing or fused raw materials. The maximum particle size of the ramming material is related to the use site and the construction method. The general critical particle size is 8mm. Most of the ramming material is not sintered at room temperature before the strength is low, the advantages of medium temperature strength is not high, only in the heating to achieve the sintering or bonding agent in the carbon compounds can only get a good combination of watering.
 
      The refractory properties and resistance to melt erosion can be obtained through the selection of high quality raw materials, adjusting the reasonable ratio and careful construction. In addition to high stability and corrosion resistance at high temperatures, the service life is largely dependent on the quality of the baking before use or the sintering quality at the first use. Such as the heating surface sintering as a whole, no cracks and not separated from the bottom, then the service life can be improved.
 
      The quality of construction of clay refractory ramming material is very important, and its quality is closely related to the use effect. Dumping castables are usually smoked with a gas hammer or ramming machine ramming, ramming a feeding thickness of about 50-150mm. Clay refractory ramming material can be carried out at room temperature, such as the use of carbon-bonded thermoplastic organic materials as a binder, the majority of the use of hot stirring method will be mixed immediately after mixing the construction, after molding according to the hardening of the mixture Features Different heating methods to promote hardening or sintering.
