Description
а Известна цементаци железа, железных сплавов, различных и г. п. в жидких сол ных ваннах, содерч:ащих нар ду с цементирующими веществами, как, например, цианиды, и расплавленные не активные соли (поваренна соль, хлористый калий, барий и т. п.). Также известно введение в сол ные ванны, которые могут примен тьс и дл цементации мелко распыленного угл .Known cementation of iron, iron alloys, and various types of liquid salt baths, containing: cementing agents, such as cyanides, and molten inactive salts (common salt, potassium chloride, barium, etc.). . P.). Also known is the introduction to salt baths, which can also be used for the cementation of finely sprayed coal.
Так как распыление угл и равномерное его распределение в ванне, особенно Г1ри последующих добавках, которые целесообразно производить в небольших количествах сообразно расходованию,--св зано с известными трудност ми, в виду стремлени уголь-: ной пыли оставатьс на поверхности и перекипать при размешивании, то по предлагаемому способу уголь вводитс в ванну путем предварительного сплавлени его с нейтральными сол ми, какие ввод т в самьш состав ванны в форме жидкости или в форме кусков (брикетов). В обоих случа х вполне обеспечиваетс Since spraying coal and its uniform distribution in the bath, especially with subsequent additives, which should be carried out in small quantities according to consumption, is associated with known difficulties, in view of the tendency of coal dust to remain on the surface and boil over with stirring, Then, according to the proposed method, coal is introduced into the bath by pre-fusing it with neutral salts, which are introduced into the bath itself in the form of a liquid or in the form of pieces (briquettes). In both cases, it is completely provided
равномерное распределение угл в ванне. Вспомогательные вещества, как, нгуфимер , едкий калий, натр и т. п., которые ввод тс в ванну одновременно с углем и расходуютс в процессе работы ванны, можно брать в количестве 1 KI на 200- 300 J древесного угл . В ванну, состо щую из хлористого ка и и натра, ввод т по мере надобности столько этой смеси, чтобы сохран ть 1-3%-ную к онцентрацию угл в 3-10% натра. . При проведений предлагаемого способа мОгут быть использованы промышленные отбросы, содержащие уголь вместе с подход щими дл указанной цели сол ми, или едкими щелочами. Дл того, чтобы, нар ду с диффузией углё рода иметь частично и диффузию азота и ускорить процесс цементации,--к ваннам , содержащим мелко распределенный угОль в качестве цементационного средства , .можно добавл ть и небольшое konfi4ecTBo цианидов, цианамйдов.и т. п., введение которых в цементационные ванны вообще известно. С применением предлагаемого способа, в котором основную роль карбюризатора играет , возможно добавку цианидов производить в количествах, значительно меньших , чем обычно употребл ютс (40- 50%). По указа«н ю автора, при помощи Ванн, составленных по предлагаемому способу, можно достигать глубины цементации в 2 мм и более. ванн дл цементации, отличающийс тем, что в жидкую ванну, состо щую из нейтральных солей, ввод т мелко раздробленный уголь, предварительно сплавленный с такими же сол ми. щийс тем, что в ванну добавочно ввод тс еще и цианистые соли. Предмет патента. 1.Способ приготовлени сол ных 2.Способ, согласно п. 1, отличаюuniform distribution of coal in the bath. Auxiliary substances, such as ngufimer, caustic potassium, soda, etc., which are introduced into the bath simultaneously with coal and are consumed in the process of the bath, can be taken in an amount of 1 KI per 200-300 J of charcoal. In the bath consisting of chloride and sodium and, as necessary, so much of this mixture is introduced in order to maintain a concentration of 1-3% to the concentration of carbon in 3-10% of sodium. . When carrying out the proposed method, industrial wastes containing coal together with suitable salts or caustic alkalis can be used for this purpose. In addition to partially diffusing carbon and nitrogen diffusion and speeding up the cementation process, to baths containing finely distributed coal as a grouting agent, it is possible to add a small amount of cyanide, cyanamide, and so on. ., the introduction of which in the cementation baths is generally known. With the application of the proposed method, in which the carburizer plays the main role, it is possible to produce cyanide additives in quantities much smaller than what is usually used (40-50%). According to the decree "by the author, with the help of Baths, compiled by the proposed method, it is possible to achieve a cementation depth of 2 mm or more. cementation baths, characterized in that finely crushed coal previously fused with the same salts is introduced into a liquid bath consisting of neutral salts. This is due to the fact that cyanic salts are additionally added to the bath. The subject of the patent. 1. The method of cooking salt 2. The method, according to p. 1, is different
