It should be emphasized that there is a single General inventive concept, cross-cutting and purposefully combines all the essential features of the claimed objects: method of making bricks and lines to implement the method. The essence of a single General inventive concept lies in the fact that the technical result achieved is implemented declared by a set of characteristics method and design features lines to implement the method.

Almost the essence of a single General inventive concept with the implementation of the declared objects is that provided the identity of the individual conditions of technological transitions for each brick in the General stream.

In Fig. 1 shows a structural block diagram of a line for the manufacture of bricks; Fig. 2 the device preparation charge; and Fig. 3 the shaping device of the brick of Fig. 4 the device of sadhika bricks-raw; Fig. 5 heat the Chica a number of well-known operations, for example, when preparing the mixture, the formation of a brick of raw, transfer it to a thermal device, drying and firing of bricks, unloading, packaging and warehousing to characterize impractical because they are detailed in the published materials.

Described in detail only the features of the realization of the distinctive features of operations. These distinctive features include the fact that initial fraction granularit to the ratio of the minimum dimension D1and the maximum size of D2granules within

7,510-31

This metered dispense pellets on the portion with the ratio of their total total surface S1with respect to the surface S2charge within

0,18 1

On the basis of a single inventive concept, the maximum volume of the portions of the granules should not exceed the volume of the body of the brick, however, in practice, preferably pellets to distribute in portions not exceeding 0.1 volume of the brick.

Then carried out in the device thin by the efforts of dimension D1pellets up to specified limits.

2,710-20,32

In most practical cases, the minimum dimension D1granules may be in the range of 0.1-0.8 mm).

When describing the technological features of the grinding charge necessary to ensure the achieved result, it is impractical to drill known means for carrying out the proposed operations, controls, parameters D1D3; S1, S2B1IN2because they do not differ from those known in the literature.

It should be noted that the three-dimensional shape obtained granules is not significant, and they can be performed, for example, in the form of "sausages".

Next, the particles are heated to a temperature T1in relation to the initial temperature T2microparticles within

1,910-177

The number of operations of the proposed method, providing mainly specified achieved results are listed operations heat treatment bricks.

Detail description of the individual operations of heat treatment is not necessary because of the popularity with the exception specification of interrelated parameters, as reflected in the claims. In detail it is advisable to clarify only added unconventional heat treatment parameters l1, l2H1h1.

The parameter l1,characterizing the trajectory length of each brick separately in the zone of the heat treatment is, obviously, a necessary complement factor characterizing this process is correlated with other parameters of the heat treatment process, such as T3, t4, T4, t5, R1, R2as together with the above parameters determine the share of thermal energy received is.

The parameter l2characterizing the local area thermal influence on each brick individually, may be equal to the size of the brick along the path of its travel. This means that the brick may be oriented in the area of heat treatment in an arbitrary manner relative to the trajectory of its movement. If there are intervals between the individual bricks that move in the zone of heat treatment, the parameter l2increases with the distance between the bricks. This applies by analogy to the parameter h1.

The parameter H1characterizing the maximum width of the field of heat treatment bricks, reflects in conjunction with h1, number of tiers and the number of threads differential characteristic of thermal field in each cross-section areas of the heat treatment, in particular the degree of homogeneity of thermal field in the area of heat treatment of each brick individually.
