Furnace mud recipe? Recipe for refractory clay

The principle of electromagnetic induction heating is that the alternating current generated by the induction heating power supply passes through the inductor (that is, the coil generates an alternating magnetic field, and the magnetic permeable object is placed in it to cut the alternating magnetic field lines, thereby generating an alternating current (i.e., eddy current) inside the object, and the eddy current makes the atoms inside the object move irregularly at high speed, and the atoms collide and rub against each other to produce heat energy, so as to have the effect of heating the article. Electromagnetic induction heating is a heating method that converts electrical energy into magnetic energy, so that the heated permeable magnetic object induces magnetic energy and heats up, which fundamentally solves the problem of low efficiency of resistance heaters such as electric heating sheets and electric heating rings through heat conduction.

At present, the induction furnace is mostly used to heat the metal parts, and the electrified copper tube around the furnace is used to produce a changing magnetic field, so that the metal parts are heated by inducing current and heat, because the temperature of the metal parts is higher after heating (up to more than 1,000 degrees Celsius), so it is necessary to smear the refractory mud on the four walls of the furnace to block the influence of high temperature on the energized copper tube. When the refractory mud is smeared on the upper wall of the furnace, due to the action of gravity, the refractory mud will sink downward, causing hollowing, which affects the thermal insulation performance of the refractory mud layer.

The soil in the recipe furnace is mainly refractory cement, plus a small amount of yellow mud, so that the furnace can be burned and roasted at a more kang furnace temperature.

So the hearth you are mainly refractory cement.

You still have the formula, and I think it will still bring you a different enjoyment by your company.

The hearth mud recipe, the hearth can hang some barbecue meat, roast chicken, because Lu Changli has some hooks on the side of the grate, and he has some food like meat, intestines, and flatbread like Mongolia.

The proportion of high-alumina bricks and clay bricks with fire clay is generally 3-5%.

The ratio of alkaline bricks to fire clay is.

The ratio of lightweight clay bricks to fire clay is 10%.

The ratio of siliceous bricks to fire clay is 5%.

The ratio of phosphate bricks to fire clay is 3-5%.

The ratio of silicon carbide brick with fire clay is 3-5%.

In short, the characteristics of refractory mud are that the higher the degree of cohesion, the better, the better the plasticity, the more convenient it is during construction.

It is best to use refractory clay, and then add some iron sand, so that it will not be bad for several years.

Refractory mud consists of refractory powder, binder and admixture.

Almost all refractory raw materials can be made into powders for the preparation of refractory muds. The refractory clinker powder and an appropriate amount of plastic clay are used as binding agents and plasticizers to make ordinary refractory clay, which has low strength at room temperature and high strength when forming ceramic bonding at high temperature. Chemically bonded refractory mud with waterhard, gas-hard or hot-hard bonded materials as bonding agents is called chemically bonded refractory mud, which produces a certain chemical reaction and hardens before it is lower than the bonding temperature of the ceramic.

Refractory mud can be divided into dry soil refractory mud, high alumina refractory mud, siliceous refractory mud, magnesia refractory mud and so on according to the different materials. Refractory mud can be divided into the following three categories according to the different binders:

1) Ceramic bonded refractory mud It is a mixture composed of refractory fine aggregate and ceramic bond (plastic clay). Delivered dry, water added, hardened by ceramic bonding at high temperatures.

2) Hydraulic bonded refractory mud It is a mixture composed of refractory fine aggregate and a hydraulic bond (cement) that plays a major binding role. Delivered in dry condition, it can be used with water and does not need to be heated when hardening.

3) Chemically bonded refractory mud is a mixture composed of refractory fine aggregate and chemical bonding agent (inorganic, organic-inorganic, organic). It can be delivered in either slurry or dry condition, hardening below the ceramic bonding temperature. According to the hardening temperature, this refractory mud can be divided into two types: air hardness and hot hardness.

Gas-hard refractory mud is often prepared with gas-hard binders such as water glass. Hot-hard refractory mud is often formulated with a hot-hard binder such as phosphoric acid or phosphate. After hardening, this kind of hot-hard refractory mud not only has high strength at various temperatures, but also has the characteristics of small shrinkage, tight joints and strong corrosion resistance.

Refractory mud is divided into two types: finished products and semi-finished products. The so-called finished refractory mud is that the raw material and clinker have been prepared in proportion by the manufacturer, and only need to add water and stir evenly according to the standard when used on site; Semi-finished or non-finished refractory mud is raw material and clinker are not mixed together, when used on site, fully mixed according to the composition of different muds, and add water and stir evenly according to the regulations.

Use refractory clay, which is the kind of cement that is at high temperatures, and put a layer of iron mesh on it to prevent cracking.
