Description

Изобретение относится к обработке, материалов давлением, а именно к спо' собам брикетирования металлической стружки.The invention relates to processing, materials by pressure, and in particular to methods for briquetting metal chips.

Известен способ брикетирования 5 металлической стружки, заключающийся в том, что стружку дробят, очищают, подсушивают, после чего перемешивают с добавлением связующего вещества, уплотняют в пресс-форме и сушат. 10A known method of briquetting 5 metal chips, which consists in the fact that the chips are crushed, cleaned, dried, and then mixed with the addition of a binder, compacted in a mold and dried. 10

В этом способе после уплотнения брикет сушат при 200-210°С в течение 5-10 мин,.х[1|.In this method, after compaction, the briquette is dried at 200-210 ° C for 5-10 minutes, .x [1 |.

Недостатком данного способа является то, что брикеты проходят тепло-г 15 вую сушку при 200-210®С в течение 510 мин.The disadvantage of this method is that the briquettes are heat-g 15 drying at 200-210 ° C for 510 minutes

Цель изобретения — повьодение Производительности за счет сокращения времени и уменьшения температуры суш- 20 ки брикета.The purpose of the invention is to increase Productivity by reducing time and decreasing the temperature of briquette drying.

Цель достигается тем, что процесс брикетиройания металлической стружки ведут с добавлением в последнюю раствора смолы УКС и фурилового спирта, 25 фосфорной кислоты и теплоаккумулирующей добавки в виде серебристого графита с последующим отверждением брикета в прессформе в течение 4-8 мин. при температуре окружающей среды. . 30The goal is achieved in that the process of briquetting the metal chips is carried out with the addition of the UKS resin and furyl alcohol, 25 phosphoric acid and a heat storage additive in the form of silver graphite in the last solution, followed by curing of the briquette in the mold for 4-8 minutes. at ambient temperature. . thirty

Пример . Подготовленную метал- . лическую стружку (дробленную, очищенную от масла и др. примесей, высушенную) в холодном состоянии засыпают в смеситель, куда добавляют холоднотвердеющее связующее в виде раствора смолы УКС (80%) и фурилового спирта (20%) в количестве 2,5-3,3 вес.ч., катализатор в виде фосфорной кислоты (Н*РО₄ плотнбсть 1,58) в количестве 0,5-0,9 вес.ч. и термоаккуЩулирующую добавку — серебристый графит в количестве 3,0-3,5 вес.ч., после чего перемешивают на протяжении О’, 5-1,0 мин.^ засыпают в пресс-форму и уплотняют с последующим отверждением брикета в течение 4-8 мин, при температуре окружающей среды. Готовый брикет выталкивают из пресс-формы.An example. Prepared metal. The wooden shavings (crushed, cleaned of oil and other impurities, dried) are poured in a cold state into a mixer, to which cold-hardening binder is added in the form of a solution of UKS resin (80%) and furyl alcohol (20%) in an amount of 2.5-3, 3 parts by weight, a catalyst in the form of phosphoric acid (H * PO ₄ density 1.58) in an amount of 0.5-0.9 parts by weight and thermoaccumulative - silver graphite in an amount of 3.0-3.5 parts by weight, after which it is stirred for O ', 5-1.0 minutes. ^ Pour into a mold and compact, followed by curing of the briquette for 4 -8 min at ambient temperature. The finished briquette is pushed out of the mold.

Claims

The invention relates to the processing of materials by pressure, in particular, to methods of briquetting metal chips. There is a known method of briquetting metal chips, which means that the chips are crushed, cleaned, dried, and then mixed with the addition of a binder, compacted in a mold and dried. In this method, after compacting, the briquette is dried at 200-210 ° C. for 5-10 minutes, .. 1. The disadvantage of this method is that the briquettes are heat dried at 200-210 ° C for 510 minutes. The purpose of the invention is to increase rtp performance by reducing the time and decreasing the dry temperature of the briquette. The goal is achieved by the fact that the process of briquetting metal chips is carried out with the final solution of the resin of the UCS and furyl alcohol, phosphoric acid and heat-accumulating additive in BjHwe silver graphite with the subsequent curing of the briquette in the mold for 4-8 minutes. at ambient temperature. Example. Prepared metal chips (crushed, cleaned of oil and other impurities, dried) in a cold state are poured into a mixer, to which cold-hardening binder is added in the form of a solution of UKS resin (80%) and furyl alcohol (20%) in an amount of 2, 5-3.3 parts by weight, the catalyst in the form of phosphoric acid (HjPO density 1.58) in the amount of 0.5-0.9 weight.h. and thermo-accumulating additive — silvery graphite in the amount of 3.0–3.5 parts by weight, and then stirred for 0–5–1.0 minutes. briquette for 4-8 min, at a temperature of circulating mediums. The finished briquette is extruded from the mold. The invention of the method of briquetting metal shavings, concluded that the chips are crushed, cleaned, dried, then mixed with the addition of a bonding material, compacted in a mold and dried, o, t and pl. then with
