The production process for sintered Red Bricks typically consists of four stages: preparing the raw materials, forming the blank, drying the wet blank, and firing the finished product are all steps in the process. After being excavated, some raw materials can be processed using water and equipment for stirring and grinding, while others cannot.
Before being ground and mixed with water, raw materials like mountain soil, coal gangue, and shale need to be broken up and chopped finely. The selection and preparation of raw materials have a direct impact on the quality of the finished product. The significance of preparation and raw materials is exemplified by the expression "raw materials are essential to the production of sintered red bricks."
After the picked red block normal substances are taken care of, they enter the frivolity studio for trim. Plastic extrusion molding is the primary method of blank forming in China. Plastic can be extruded in three different ways. What is the distinction between hard plastic expulsion shaping, semi-hard plastic expulsion embellishment, and plastic expulsion forming?
These three extrusion techniques are based on the varying moisture content of the molding. When the moisture content is greater than 16%, wet billet molding is known as plastic extrusion molding. When the moisture content is between 14 and 16 percent, the process is called semi-hard plastic extrusion molding. When the moisture content of the hard plastic is between 12 and 14 percent, extrusion molding is used.
Blank forming includes: A red brick extruder is not used to process the raw materials before they enter the molding shop. Instead, equipment is used to feed, mix, add water, and grind them. The molding red brick machine is used to form the qualified mud and wet billet. During the process of forming, shape and structure should be achieved. The shape is the first step in making Facing Bricks. The quality of the formed body directly correlates with the quality of the finished tile.
After being formed, the wet billets at the molding plant need to be dehydrated in order to dry. During the manufacturing process of sintered red bricks, the wet blank can be dried in one of two ways: Methods of natural and artificial drying The process of natural drying involves placing the wet billet on the billet stalk in the natural drying location, manually inverting the code, and utilizing the atmosphere to turn the cold billet into a dry billet.
Artificial drying is the process of drying a wet billet in a well-equipped artificial drying chamber. Artificial drying rooms can be divided into three groups: chamber, small-section tunnel, and large-section tunnel drying rooms, respectively. Before being dried in a chamber, the wet billet is placed, either manually or mechanically, on a drying truck. In most cases, the heat medium in the drying chamber is the waste heat from the hot blast stove or sintering kiln.
Regardless of the drying method used, the blank must not be deformed or chapped during the drying process. If the wet billet is unable to maintain the product's appearance while drying, it will result in a high oddball rate, falling result, and inflated cost of the finished red block, all of which pose a risk to the company's financial capability. During the process of making Red Brick, this exemplifies how important it is to dry wet billet.
If the residual moisture rate after drying is less than 6%, the wet billet could be fired in the baking kiln. Typically, a tunnel or Hoffman kiln is used for roasting. The Hoffman kiln receives the red brick code by hand, which is then roasted over the fire. The red block code is physically or precisely positioned in the furnace truck when using a passage oven. The kiln car moves from the tail of the kiln to the head of the kiln.
The uncooked red bricks from the kiln car are roasted into red bricks. The oven truck isn't the main thing the cooking fire in the furnace moves. These two requirements must be met regardless of whether a tunnel or a Hoffman kiln is used: 1. Never produce an unburned red block by utilizing an underfire. Using a large fire to make coke red brick is never a good idea. The expression "roasting is the key to the process" serves as an illustration of the significance of roasting in the process of making red bricks.
The process of sintered red brick consists of four steps. In conclusion, molding is regarded as the foundation, drying is guaranteed, roasting is the key, and the raw material is crucial. These four components are interdependent.
