Sawing sawmill on tape – an important stage of the material. Poor cutting threatens to breach the specified standards for a particular type of material. High-quality cutting, in turn, involves not only compliance with standards, but also work with the wood of any species. The current market for woodworking machinery is widely represented tape power-saw benches, possessing qualities such as: – high precision cutting – a greater yield of timber than Multiblade machines – compact and light weight – mobility, not to mention your availability, low price and ease of use. The consumer becomes a legitimate question: how to choose the best equipment to work.

How to buy a quality sawmill factory tape, rather than a pig in a poke. First of all, it is necessary to examine products offered on the market. What types and brands of the most common band sawmills and exploited. What advantages and benefits of a product of a manufacturer. However, careful study of all cons.

Assess the conditions under that the selected band sawmill will be used. An important indicator of the success of future operation of the machine – is the availability of the warranty period. The next, equally important indicator is the possibility of holding commissioning. Reliability chosen sawmills should be confirmed not only the accompanying documentation – learn customer feedback. Maintainability – a single element that determines the quality and "Security" buyer. Please note that the lack of maintainability of equipment later require costly maintenance and repairs. And in some cases, can lead to stagnation in production and material losses. Thus to buy a sawmill in fact not so simple. OOO "Golden Section" – band sawmills and machinery otsilindrovochnye production and sale. .

The Color

Fuel slag and fly ash differ in composition and properties depending on fuel type and method of its combustion. Fly ash is a fine-grained material with small particle size, which allows its use for a number of industries without grinding. A characteristic feature is the presence of ash in it for about 5-6% of unburned fuel, and iron, mainly in the ferrous form. Slag particles range in size from 0.2 to 20-30 mm. In furnaces with liquid slag removal slag is obtained in granular form. It is characterized by glassy structure.

Characteristics and composition of the slag slag – artificial silicates. They consist of oxides of silicon, aluminum, iron, calcium, magnesium, manganese, sulfur, and others. These same oxides contained in the natural deep rock formations. Depending on the proportion of oxides, as well as on the conditions and cooling rate of slag slag melts may have properties of granite or volcanic pumice. And the color of slag are close to the rocks. They can be blue-black, snow-white, green, yellow, pink, gray.

Often they have a silver, pearl and purple hues. Slag can be dense and porous, hard as basalt and tuff as light or coquina. The density of the slag varies from 800 kg/m3 to 3200kg/m3. The proportion of slag, ie, the weight of its substance, is close to the weight of natural stone materials and is 2.5-3.6 g/cm3. According to the chemical composition of blast furnace slag can be divided into basic, neutral and acidic. The basic module includes slag from the basic (M = (CO + MgO) / (SiO2 + Al2O3)), greater than one, to acid is less than unity.
