In this study, the effect of cold rolling process on the microstructure and texture evolution in 1wt. % Si non-oriented electrical steel was investigated. For this purpose, all samples were processed through single-stage hot rolling at 1100 ° C and two-stage cold rolling (cross rolling and unidirectional rolling) with intermediate annealing at 650 °C for 35 seconds. Finally, all of them were fu...

The paper discusses the problems of plant protection from weeds and need to improve methods weed control in production agricultural products, describes used. design an improved fire cultivator for burning gardens vineyards by thermal method, as well technological process its operation, is presented.

Cold rolling process of a major transformation in the form of sheet metal and a wide range of steel products are produced in this way. Elastic deformation during cold rolling working rollers and the inevitable increase in the rolling force. In this study, the effect of elastic deformation during cold rolling mill rollers working on the reciprocating back and forth in tandem with the presence of...

The depth of tillage and its uniformity are the main performance indicators chisel cultivators, as well all machines. Only when these at level demand, favorable conditions created for uniform development ripening crops throughout field their high yield. article theoretically explores problem ensuring a smooth movement suspension cultivator along with working depth. results show that given requi...

Weeds compete with crops for water, nutrients, and light consequently, have adverse effects on the crop yield overall productivity. Mechanical weeding is most common non-chemical method weed control, which applied in organic farming, cultivator implement mechanical weeding. This study aimed to design develop an innovative active tool optimize cultivation depth, can avoid damage roots improve ke...

Abstract Tractors are used for various types of field work, as well transport on public roads, in difficult and changing environmental conditions. The main goal the study was to analyze changes trace elements engine oil during works. For this purpose, oils from two tractors were selected study. These coupled with: a cultivator, reversible plow, tillage-sowing unit, trailer. samples taken at beg...
